Picked up an 80s space mountain shirt from the coolest vintage store last night. More shops should use Pokémon cards for their price tags

Lots of awesome OS for the PDS posts flying around today, but what about a PDS in the OS? Here's a peek at the native Linux rewrite of @aetheros.computer, built on NixOS with PDS backed user accounts and experimental support for spaces. Still WIP, but stay tuned for more info later this year...

Got my Retroid Pocket Nova yesterday and it’s def become my favorite handheld for retro gaming. It has a 4:3 OLED screen and emulates everything from 8-bit to 128-bit consoles flawlessly. It’s also android based and incredibly easy to hack on 🤩

Added drafts and a new world layer system that lets you post Brickster creations to the BB map. Also has an AR feature for viewing your creations in your physical space. I have a few ideas on how i can expand this layer system with atproto, but would love to collab with anyone thats interested 🤙

Having so much fun messing around with this. I wanted to stress test the 3d editor for @brickster.at and ended up making a Death Star trench diorama. The editor has a bunch of new builder tools and you can now invite up to 12 people to edit together using your atproto handles.

There are many things being built on atproto. Many of them won’t get adopted or thrive. And yes, many are built without user research. It’s OK? Don’t use things you don’t want to. Promote things you like. And build something yourself if you feel like it. Do it the way YOU want it to be.

New atproto app idea I demoed yesterday where you record what you’re grateful for and tag someone. Each orb is a recording, and is used to power a generative synth for a dynamic ambient soundscape. Definitely zoned out to this last night 👽
