I've seen a video presentation on how a 96 kB game was created:

and I've tried the texture generation in Lisp:

But for the last big pictures with #'olympic-rings it took half an hour
to calculate the image. How can I improve it? I think the funcalls are
too slow, perhaps it can be assembled together with direct function
calls with some macros at compile-time? And the values should be cached,
perhaps with some memoizing concept, because currently too much points
are calculated multiple times when chaining #'blur and #'emboss.

My goal is to adjust the parameters in real-time with an interactive
GUI, like in the editor for the kkriger game:
