Can someone make this 3D ball bounce at the click of a button and after 2 seconds stop the ball in mid air and make a random number appear on the face of the ball while the ball becomes bigger?/nearer to the screen? Thanks.

    Is there any way to create bouncing balls in Curl?

See my attached applet for part of what you want to do. You could substitute an image of a ball instead of the image I used.

I looked at the documentation and it seems sphere is used to distort
    a picture or input.
Seems easier for me to just to used flash... is it correct?

Many animations are probably easier to do with Flash than with Curl's current
