Adjust spectrum to yield different color gradient. My attempt to model color spectrum on Fischer's Lovebirds. Choose feather size. Spacebar changes feather from realistic to cartoon. Scratchblocks make sounds based on tiling.
No birds harmed in acquiring feathers. The feathers are laid down as columns of rows. The colors are a function of the Y position. Image of Fischer's lovebid taken from wikimedia commons, a photo Peter Békési (I erased the background and perch). I tried cartoon feathers and real feathers dyed red. Spacebar shifts between the cartoon and real.
