Possibly incorperate an automatic fading trail turn down dependant on lag? Also, you definately need to make it start as just the image, the way at starts looks kinda bad and random. So yeah, start unbroken, automatic fading trail turn down and it'd be a good preloader :P

Slightly laggy.
I'd like to see a less intense option. Awesome as is, but I'd like to see the choice.
Would it add to lag if you were to make movement based on elapsed time rather than a per-frame thing? Or is that already how it's done anyway?
