Have you seen Iain’s Ping Clang example in the FunAndGames menu? It’s great fun and adds a level of physics to the scene too. In terms of throwing stuff around the screen, check out the custom xypad I creating using only Cabbage and Csound code, i.e, without using an actual xypad.
This could also be done with SVGs too, but I think I would still make each component an image that draws a single SVG rather than try to create one mega SVG that renders the entire scene.
