I was messing with shapes and I got a sqare moving, thats nice, so I said to myself: What about I create multiple rectangles at once and make them move on the screen.

I used two random functions to set the size, color and speed of said rectangles random, I wanted tons of colors on my screen.

Okay, I advanced a bit, now it displays random rectangular shapes of various colors BUT they don't move at all, once the next shape is loading the rest stops moving I think thats the problem. Is there any way for me to make them move permanently?

Thank you

PS. BONUS:  just for testing and learning, is there any simple way to make them bounce off on the border of the screen?
