It runs about 192fps for me. Use whatever bitmap you want

Left click to draw green pixesl, right click to draw yellow pixels.

i get a "memblock position outside range" error if i click anywhere on screen, even on the object. it says line 48 i think

is your image a square? the bitmap i used was 36x36

I get the error too if i use larger images. i'll try to see what it is.

maybe changing thw width,height,depth position in the memblock would help

Those positions are always the same for bitmaps. Honestly, I haven't been working on this since I posted it. It does what I needed it to do.
