For a more old school feeling, replace 4*t with 4*t|0
u/sigveseb

Nice colors, reminds me of the gameboy color palette.
u/sigveseb

(Did you delete an older version of this dweet?)
u/iverjo

Yes, I deleted the old school version that quantized the colors with 4*t|0 and put it as a comment instead :)
u/sigveseb

Ok, that was was the one I meant to comment on about the gameboy color palette ^^
u/iverjo

Does it deserve to be a separate dweet?
u/sigveseb

The more the merrier :P
u/iverjo

Ok, sure :P

Storing the gfx data like that is sweet! So nice to see if without obfuscation!
u/BriSeven

if you deduplicate the symmetry, rotate it (so that it is 8 rows of 16 pixels), and prune out the two rows that then are just zeros... we can shave the graphics data all the way down to 鰜鹞廾皶㜷彟
u/BriSeven

which would be worth it if you can find a way to undo all that which isn't more code than the characters we save
