Game of sand This game is great fun. I'm not sure whether I understand it but that is irrelevant. You set up walls and other things to divert a few streams of falling sand. Easier to understand if you see. http://chir.ag/stuff/sand

Moving Red Square Another simple but fun game (fun for some, a real pain for others). Use your mouse to move a red square inside a box and four 'blocks' begin to move about. You must prevent the red square from touching anything. If you can do this for 18 seconds, you're good. http://members.iinet.net.au/~pontipak/redsquare.html
