So we’ve got this thing where you have a painting that looks like a Mondrian, and you can add/remove the red and blue colours. The lines shift according to these colours: red increases pressure (hot), blue decreases it (cold). The objective is to align the yellow rectangle with its ghost image. You can try it online here.

It’s not much fun, mostly trial and error, and we’re out of ideas for fixing it. We might just start over, although we don’t have any alternative ideas either.

Minimalism is hard!
