Click. Yeah... I don't know what to call this. It's a transition which zoom in the current costume, while superimposing a grid with a slight fisheye effect, then zoom out with the next costume. Anyway, I like it. It's using the pen to stamp, but it could be modified to use clones. All code by me (@kriblo). Images are from the world wide web, vectorized by me. Sound is "Machine" from the Scratch library, but with the pitch effect set to -200.
