You're good, but are you that good lol!
I found it interesting how you converted the lwax's back into pixels not realizing the default ones were created using pixels in the first place
It makes sense to make the default ones in Photoshop though as they're not tied to any one button layout so that's why I made them that way. I should really make some colored ones at some point.
It might be cool to add png importing to your Animation Editor. Another feature would be to allow the user to select groups of LED's then apply different waveforms (like sine, triangle, square, and sawtooth) to lerp the colors in some some way. I also remember sending you some code for a classic plasma effect which looks great too. Not sure if you ever implemented the effect into LEDBlinky?
