Simple 3D game

Here a very simple 3D game, just try to click as may time as possible the 3D Rebol logo. My record is 104:

Here the source code:

REBOL [
title: "Little 3D Game"
date: 29-Nov-2009
file: %3d-game.r
author: Nick Antonaccio
purpose: {
Try to click the bouncing REBOLs as many times as possible in 30 seconds.
The speed increases with each click! The 3D logic and calculations in this
script were taken directly from Gregory Pecheret's "ebuc-cube" script, at:
http://www.rebol.net/demos/download.html
This script can also be found in the tutorial at http://re-bol.com
