Aerobat resampled onto diagonal pixel grid is a pretty cool look

(prob need to click to actually see it on twitter)

The "correct" way to do this would be rotate your camera 45 degrees, render to a square, point-sampled, low-res texture, then draw it rotated back and scaled/cropped to screen aspect

p easy to do in Unity or whatever

Doing that with Aerobat's engine is a giant pain though so I just slapped on this hilariously inefficient shadertoy postprocess thing I made ages ago lol

Instead of rendering at a super low resolution and getting awesome performance, this way I can render at full resolution and then make 256 texture samples per pixel to *fake* low resolution!

Oooh here's a cool modification: Each color channel is resampled onto a grid rotated 60° off from the other two

Sorta like CMYK screentone patterns but additive and made of squares

(again, prob need to zoom in before twitter shows it big enough to see)

At lower grid resolutions it gets really abstract and cool

One problem here is that perceptually speaking R, G, and B have wildly different luminosities, so the whole image ends up mostly looking like it's tilted at whatever angle G is set to

This had never occurred to me before now, but C, M, and Y have much more similar luminosities, which probably explains why CMYK screentones don't generally exhibit strong directional artifacts. Neat!
