This project tries to imitate Scratch itself: There's a creature vaguely resembling a cat. Then there are three shapes that look like they might belong to a jigsaw puzzle. Plus, there's a green flag... Hmmm.... Once the project is started, the cat-like creature gets animated. Now click on any jigsaw puzzle shape. this will change the way the cat-thing moves. Try dragging the puzzle-shapes around. You can actually snap them together in any order you choose. Once at least two blocks are snapped together you can press the green flag to execute your program in top-down order. Did I mention this project is a tribute to Scratch itself?
