When you push 0 (zero), the cat goes to x-offset / 2 by y-offset / 2. The cat then starts moving, turning at a certain angle and moving a certain number of steps. This number of steps increases constantly, giving a spiral effect. Also, a variable called redo-target increases. When you push the Spacebar, redo-target stops increasing and the cat goes to 0 - x-offset / 2 by 0 - y-offset / 2 and starts again. Then a number called redo-control increases. The second spiral stops when redo-control is equal to redo-target. Press 0 (zero) to begin. When you press the Spacebar, it goes to a point you defined with x-offset and y-offset. Then the spiral starts again. It stops when the spirals are equal in size. UPDATES: v0.01: Super-bug: Angle variable wasn't working. Fixed that. Also actually made Zero start the spirals >.< v0.02: I added a doohickey that tells the speed in pixels per decisecond (10ths of a second) that the spiral was made. I'm not even sure it tells the correct speed.
