A simple 16x16 dot animation from simple math rules

Tixy is amazing! I built something very similar:<p><a href="https:&#x2F;&#x2F;muffinman.io&#x2F;pulsar&#x2F;" rel="nofollow">https:&#x2F;&#x2F;muffinman.io&#x2F;pulsar&#x2F;</a><p>I wanted to create animations for my LED matrix screen, and I couldn’t find tixy anywhere. Only after I built pulsar I found it again.<p>Another similar project is <a href="https:&#x2F;&#x2F;sliderland.blinry.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;sliderland.blinry.org&#x2F;</a> which uses HTML sliders.<p>Fun stuff!

I loved tixy when I first discovered it a few years ago so created this <a href="https:&#x2F;&#x2F;www.mathsuniverse.com&#x2F;tixy" rel="nofollow">https:&#x2F;&#x2F;www.mathsuniverse.com&#x2F;tixy</a> (with permission from the original author) with puzzles to solve on the tixy grid. I use it with my computer science students who get really into it.

I made a drawing app with programmable brushes inspired by tixy:<p><a href="https:&#x2F;&#x2F;fig.sonnet.io" rel="nofollow">https:&#x2F;&#x2F;fig.sonnet.io</a><p>It’s pretty fun because the shape dynamics are time, and not pressure&#x2F;tilt based, so you need to draw in a rhythm.<p>Here’s how they work and how they’re implemented:<p><a href="https:&#x2F;&#x2F;untested.sonnet.io&#x2F;notes&#x2F;fig-tree-brushes&#x2F;" rel="nofollow">https:&#x2F;&#x2F;untested.sonnet.io&#x2F;notes&#x2F;fig-tree-brushes&#x2F;</a>

A lot of these tricks I first learned from Noah Spurrier’s acidwarp.exe VGA demos in the 90s.<p>Now I’m wondering who first published these trig function pixel paint tricks. Somewhere between HAKMEM munching squares and the 80s demoscene?

Wow this is extremely well done! All the defaults are chosen so well to make simple inputs get pretty results. The interpretation of the result value, the scale of `t`, the colors, it&#x27;s all not trivial at all to get right! Hats off

That&#x27;s really fun! I love minimalist sandbox ideas like this.

Is there a pattern or animation you can manually animate on those dots that can’t be represented by an equation?

I’m considering that as a load screen animation. Bunch of different functions, and the user will be entertained.

this is beautiful. i love it so much :)

I am impressed by both the website and how good people here are at trig.

&gt; &#x2F;&#x2F; hit &quot;enter&quot; to save in URL<p>There&#x27;s no enter on Android Chrome on phone.

Is it possible to create a tixy QR code that contains a link to itself ?

Would be cool to implement this physically as an array of iris diaphragms

Why is the &quot;=&gt;&quot; going in the wrong direction ?

Isn&#x27;t i == x + 16*y? Why is it needed?

Shame that 32 characters is a bit too few to make a raycaster. 128 would be quite enough I think.

really impressive, keep up the good work

I feel so dumb. How can I make this zoom centered on the grid?<p><a href="https:&#x2F;&#x2F;tixy.land&#x2F;?code=Math.sin%28x*t%29%2BMath.cos%28y*t%29" rel="nofollow">https:&#x2F;&#x2F;tixy.land&#x2F;?code=Math.sin%28x*t%29%2BMath.cos%28y*t%2...</a>

is this just shaders but not?
