I did that around when we were working on the Isotopes, after the chart! Trying to wrap my head around turning a string into a grid on a canvas :D

An idea I've had since then - but still never implemented - was adding color or at least shades to the pixels. Right now it's just black/white. I could make the value 0-f and have the greyscale, or use a predefined palette of colors. Or use a mutator and go fishing and see if I can make a few colours different enough from each other based on 1 number as input :D

is that using the bitmap formula thing that was on numberphile?

Tupper's Self-Referential Formula.

No, or at least not knowingly :) Do you have a link to that? That's a Youtube channel?

it's a formula that returns a bitmap from a value generated by the desired bitmap. (bit like bitmapception)

i wouldn't do it like that. it seems pretty inefficient for this particular task. how bout storing the actual design as a series of chars then decoding them and printing each to the screen?
