Shameless plug.. I made a super slow motion 184 byte aperture grille (Trinitron) animation:
https://www.dwitter.net/d/12335 https://www.dwitter.net/d/12335
And a more recent one with more interesting motion at faster speed:

It is interesting how even as an animation it makes it look a lot smoother than the raw upscaled pixels of the same simple graphics.
- codetrotter 6y agoThe second one does not run for me on an iPhone X, but the first one does.
- tomxor 6y agoI can only speculate as to why because it's safari which i don't have. If the eval is throwing an exception it's probably something to do with the unicode encoding that packs 2 ASCII chars into each UTF16 surrogate pair - the second one ultilises slightly more of the 20bits available and some UTF16 implementations/interfaces are buggy. You could replace 'eval' with 'throw' and see if the output looks like sane JS

- tomxor 6y agoHah, actually that code is correct (Although I realise it probably looks like gobbledygook :D) so it disproves my theory. The code is mostly arithmetic, so the only thing I can see which could be implementation sensitive is the canvas fillStyle HSL string, which omits commas and spaces since the % postfixes are enough to delimit the saturation and luminance, but obviously this depends on the canvas interface implementation.
- codetrotter 6y agoI looked into it and this turned out to be the problem exactly. If you change the part of your code where you have hsl(${i*120} 99%${K*99}% To instead hsl(${i*120} 99% ${K*99}% (That is, by not omitting the space after 99%) Then it works in the versions of Safari that I tested; Safari 14.0.3 on macOS Big Sur 11.2.2 running on a MacBook Pro M1, and Safari on iOS 14.4 running on an iPhone X.
