A another application of my motion tweening blocks in painting program. Instructions are in the project on start. It's a simple painting program, nothing special there. My main goal was to make animated tool icons. Animation makes opening the tool panels much smoother, creating a lively wave effect.
Hiding icons helps saves screen space, making room for other user interface elements. The color pallet for example is 80 pixels high, though I've reduced it to a hotspot that is only 15 pixels high. Please see my other related projects for more info: https://scratch.mit.edu/projects/44237598/
