Got it downloaded Tom, looks cool, here's the best way (in my opinion) to acheive this effect, post production using After Effects or similar programs, if it just gonna be a still image use photoshop or painter or whatever, but if its animated you would save yourself a LOOOOOOOOOT of render time doing it in post production, make your base scene then add all the bells and whistles in post.

Do atleast one thing a day that scares the hell outta ya!!
