sprawld @sprawld.sprawledoctopus.com · 01/03/2026This rule is everywhere. It's true with prefixes: so you can't be undisunited or undishonourable, but also suffixes: you can be unmerciful but not unmerciless (ie nice). But it's far wider than that: words that have negative meaning cannot be negated. You can be unloved but not unhated 100
sprawld @sprawld.sprawledoctopus.com · 01/03/2026So, onto the paper. It goes on to - bear with me - un-unlockable. Here there is no ambiguity. An un-unlockable padlock is a padlock I can't unlock. The reason the ambiguity is resolved is a general rule of words: *you cannot stack two negative elements on top of each other*. Only one tree is valid 100
sprawld @sprawld.sprawledoctopus.com · 01/03/2026An unlockable padlock could be "a padlock I can unlock" or "a padlock I can not lock". The ambiguity arises because you can assemble the word in 2 ways. Here are both in tree diagram form. The negative-adjective (neg-adj) is the padlock that cannot be locked. 100
sprawld @sprawld.sprawledoctopus.com · 03/01/2026Mostly because that's exactly what he said last time he had to support the most flagrant breach of international law 100
sprawld @sprawld.sprawledoctopus.com · 04/09/2025It doesn't seem (from google trends) that anyone's coined this term so I'd like to: Twitter's been slopified 030
sprawld @sprawld.sprawledoctopus.com · 29/07/2025@watsoncomedian.bsky.social @alexhorne.bsky.social absolutely convinced Tim Key is manifesting reality 020
sprawld @sprawld.sprawledoctopus.com · 22/02/2025Still playing around with fractals, also tried out adding camera blur, this is a bit of both #Bauble 000
sprawld @sprawld.sprawledoctopus.com · 19/02/2025This week in #Bauble The Mandelbulb fractal! (orig algorithm by Inigo Quilez) 100
sprawld @sprawld.sprawledoctopus.com · 28/01/2025So I made a bauble world, took the shader code and added my map projection function. There's a page with it here sprawledoctopus.com/bauble-peirce/ . May be slow based on your graphics card, but it looks a bit like this (press arrow keys & w & d to move around) 000
sprawld @sprawld.sprawledoctopus.com · 28/01/2025There are lots of map projections and they all do the same thing: turn a sphere into a flat shape (usually a rectangle). You can invert this logic, and for a rectangle look outwards at the spherical angle. I wrote some shade code that does this and then used panoramic images 110
sprawld @sprawld.sprawledoctopus.com · 28/01/2025But the point of Bauble is it creates shader code - code that runs on a graphics card - live, not just a video. I've done one bit of shader code before with that most venerable of map projections: the Peirce Quincuncial projection sprawledoctopus.com/panorama/ 100
sprawld @sprawld.sprawledoctopus.com · 28/01/2025I've been getting my Game of Thrones credits on (the only part that was consistently good throughout) 100
sprawld @sprawld.sprawledoctopus.com · 28/01/2025I've been playing with shapes, made some chess pieces. Now I want them to make random (but legal) moves, rabbit holes are everywhere. 100
sprawld @sprawld.sprawledoctopus.com · 28/01/2025Bauble: Week 2½ (I wanted to post on the weekend but couldn't stop playing) 100
sprawld @sprawld.sprawledoctopus.com · 19/01/2025I'll hopefully post more over the coming weeks, but here's my current best: Umibōzu 140
sprawld @sprawld.sprawledoctopus.com · 19/01/2025SDFs have other tricks, like being able to repeat them endlessly in a single stroke. They don't have to stay identical, here I give them different colours. LOOK HOW GOOPY IT GETS 130
sprawld @sprawld.sprawledoctopus.com · 19/01/2025Back to Bauble: what it allows is to create things so quickly and simply. I'd watched a video about SDFs which gave an example of a ball passing through a rotating cube. Once it was over I opened Bauble and within minutes I'd done it 120
sprawld @sprawld.sprawledoctopus.com · 19/01/2025This generalises to 3d, and you can combine objects together, either union, intersection or subtract one from another. And when combining, you have the option to smooth out. This is the first joy with SDFs, because everything's a distance your world is built out of clay, you can smoosh things 120
sprawld @sprawld.sprawledoctopus.com · 19/01/2025There are SDFs for various shapes, the thing to note is how the distance field ends up softening. Take the rectangle: going outward from the sides produces straight lines, but at the borders it rounds off. So you can round off an object just by adding a fixed number to your distance 120
sprawld @sprawld.sprawledoctopus.com · 19/01/2025Bauble allows rendering of 3d spaces with "signed distance function" (SDFs). This just returns a value of how far away any point is from it. Here's a representation of the SDF for a circle, the white represents distance 0, the bands represent 1, 2, 3. Inside the distance is negative (hence "signed") 120
sprawld @sprawld.sprawledoctopus.com · 11/01/2025For my first play I went with the classic: a twisting octopus. I got this far 010
sprawld @sprawld.sprawledoctopus.com · 31/12/2024Spent the last few hours iistening to www.twitch.tv/clubfortyfour and coding this sprawledoctopus.com/nye2024/ Happy New Year all 010
sprawld @sprawld.sprawledoctopus.com · 01/12/2024I'm trying to get some of the projects sitting on my hard drive 90% complete and finally put them online. Today it's everyone's favourite: Flag Game sprawledoctopus.com/flags/ 100
sprawld @sprawld.sprawledoctopus.com · 28/02/2024it's official: the government says you should rewrite your project in Rust 060
sprawld @sprawld.sprawledoctopus.com · 18/09/2023Ouroboros v5 sprawledoctopus.com/ouroboros/ - added customise board (because I'm not the boss of you), somewhat more mobile friendly (you can rotate the tiles) and desktop friendly (right-click rotates back) 010
sprawld @sprawld.sprawledoctopus.com · 11/09/2023Ouroboros v4. Now with 5 types of grid, hover-help on the edges and (obligatory) dark mode. sprawledoctopus.com/ouroboros/ 021
sprawld @sprawld.sprawledoctopus.com · 11/09/2023the dodecahedron pattern really broke my brain, but i finally cracked it (the problem that is) 110
sprawld @sprawld.sprawledoctopus.com · 20/08/2023I will not be deterred, I think there are more tilings that will work, I just need to avoid triangles. I'm trying the dodecagon next 000
sprawld @sprawld.sprawledoctopus.com · 20/08/2023it was serendipity that hexagon tiles made for an enjoyable puzzle, then I got lucky twice with the octagon/square pattern which is, if anything, better. 100
sprawld @sprawld.sprawledoctopus.com · 20/08/2023the eventual results are.... not that pleasing! the triangles really hamper the snake from twisting over itself which makes for a fun puzzle 100
sprawld @sprawld.sprawledoctopus.com · 20/08/2023have spent forever getting my head around this this tiling, the shared squares and triangles really broke my brain 110
sprawld @sprawld.sprawledoctopus.com · 13/08/2023ouroboros v3 sprawledoctopus.com/ouroboros *somewhat* mobile friendly, with choice of hex, square or octogon tiles 020
sprawld @sprawld.sprawledoctopus.com · 11/08/2023octogon + squares... now we're talking (wrapping isn't working correctly yet) 100
sprawld @sprawld.sprawledoctopus.com · 11/08/2023triangles: inherently boring - the snake can't cross itself. Once it's crossed a triangular tile, 2 out of the 3 edges are already used. 100
sprawld @sprawld.sprawledoctopus.com · 11/08/2023experiments with other tile types squares with 2 or 3 points: messy and unappealing 100
sprawld @sprawld.sprawledoctopus.com · 05/08/2023not sure i've got the hang of posting link cards. anyway you might feel bad laughing until you realise they're just repackaging a podcast anecdote 000
sprawld @sprawld.sprawledoctopus.com · 05/08/2023Ouroboros v2 sprawledoctopus.com/ouroboros added a hint button, an animation for the start & when you win and improved the path algorithm. 000
