Thanks for the inputs, I think I'll PhotoShop them over the weekend and post them. I didn't think about getting the stick-ons for test purposes, sounds like a good idea. Of course, this lead to another idea: installing LED type lights on the inside of the portholes. The LEDs would fire when the cylinder fires (one porthole per cylinder. I would need to scale/divide the firing rate, otherwise they would be pretty much on all the time. Just something fun to tinker with, it may be a bit too goofy, but easy enough to remove/turn off.
