Animation in LOGO is really pretty easy. This example uses three frames. The first frame is the guy in the up position. The second frame is in the middle position and the last one is the down position. You just create each one in edit and then rotate them in a repeat that looks like this:
repeat 100[up middle down middle]
The middle frame is used twice since it serves as a transition in either direction.
The illustration on this page was first created using LOGO and then saving the logo images as bitmaps. The bitmaps were trimmed in MS Paint and then placed into animated GIFs using Lake Clear Animato.
