Ollin traces the caustics, the light the glass bends onto the table. It splits that light by color like a prism, so little rainbows spill out around the drops.

Another reimplementation of a 2021 sketch, where gooey blobs moved on Lissajous curves. Now they melt together into drops of dark glass. S/N: 2026.014 #creativeCoding #generativeArt #dailySketch #ollin #caustics

Now the blobs are metaballs, soft shapes that merge when they get close, and Ollin stacks their outlines into a 3D solid with marching cubes. The flat top is the newest shape, and each white ring is an older outline.

Three lines moving on Lissajous curves. The colors come from a complex logarithm, implemented in a shader with Ollin's complex number helpers. Each pixel adds up the angles from one end of each line to the other. S/N: 2026.012 #creativeCoding #generativeArt #dailySketch #ollin #complexNumbers

Each line is added as light, like a long exposure, so the color builds up where it slows down. The space between them gets a Laplace fill in Ollin: each empty pixel becomes the average of its neighbors.

Each dial has a different number of rings, with its own widths, speeds and order of the five colours. This time it uses Ollin's depth-of-field rendering, so the focus moves across the grid.

Following up on yesterday's sketch, another reimplementation of one from 2022. I was playing with composition and tried the dials packed like a honeycomb. S/N: 2026.007 #creativecoding #generativeart #dailysketch #ollin #bokeh

Each ring is broken into short arcs and turns at its own speed. This time it uses Ollin's depth-of-field rendering, so the focus moves back and forth through the rings.

Another depth-of-field sketch with a five-sided aperture. The tower is a stack of square outlines, each turned a little from the one below it. Lines and dots fall through it, and the ones out of focus come out as pentagons. #creativecoding #generativeart #dailysketch #ollin #bokeh

The ground is parallel lines over hills made with noise, and the small lines going through it slide up and down. The particles land close together near the focus and spread out away from it, so those parts look soft.

Same depth of field technique as yesterday, particles instead of a blur filter, now on a landscape made of lines. #creativecoding #generativeart #dailysketch #ollin #bokeh

There is no blur filter here. Each line is drawn as particles, and each particle goes to a random place inside a sphere that grows as it gets farther from the focus. On their own they are just scattered dots. Each frame contains about 232 million of them, and together they simulate a real lens.

I wanted to understand the depth of field technique in Domenico Bruzzese's Blurry, so I made my own version of one of his demos in Ollin. S/N: 2026.003 #creativecoding #generativeart #dailysketch #ollin #particles #bokeh #swiftlang

If you speak two languages well, have you tried counting to 10 in alternating languages? I found it surprisingly mind-bending.

What hurts the most is how suddenly he left. But in truth, no one ever really leaves completely. We love and miss you so much, Pá’. Rest in peace. We carry you with us and will remember you always.

Edgardo Avilés-López @eavl.co · 18/06/2025

I hope I can be the same kind of example for my children, and give them the same love he always gave us. We never lacked anything. He always reminded us to keep studying, to keep working, and to always move forward.

The family adventures we shared. How we’d all come home for Christmas and be together again, even if just for a while.

Edgardo Avilés-López @eavl.co · 18/06/2025

…or how I’d see him working late at night preparing the school schedule or grading papers while I pretended to be asleep in the room where we all slept together. The naps we’d take in the air conditioning after school.

Edgardo Avilés-López @eavl.co · 18/06/2025

I remember the care he put into every project he took on: the garden he loved so much, the meals he cooked, the little blue Datsun (our other brother) that he restored and cared for deeply…

Seeing him in his lab coat made me believe that all scientists wore one, although I later found out that wasn’t really the case (except for that week we visited the local hospital during a research trip from graduate school).

Edgardo Avilés-López @eavl.co · 18/06/2025

I remember how, at the end of the school year, he would bring out the human body models in the biology lab—models that used to scare me—and the experiments he performed in front of everyone.

But I owe my career to my dad—and that curiosity he always had for every single little thing.

Edgardo Avilés-López @eavl.co · 18/06/2025

My dad had a collection of thin 5-inch floppy disks with games and 16-color animations covering all the school classes. I think it was a Commodore 64. What I clearly remember is that all the programs were written in BASIC, even though I didn’t understand anything about programming yet.

Edgardo Avilés-López @eavl.co · 18/06/2025

Among many memories, I remember when he started managing the computer lab at the middle school. The only computer I had seen until then didn’t have a monitor—you had to connect the cables to a VCR and then to the TV.
