Thank you - I really love doing this, and am honored that you guys dig it. I've had a couple questions about "filters", so before I go off and airbrush them on, I'll prepare the camera and do a little tutorial. Something in the next week or so, time permitting, etc etc.
Oh - and the engines have a red led, with an amber led on either side (3 total in each burner can). The red is steady-on, and the ambers flicker randomly. Looks totally cool - like they're actually producing thrust.
