That stuff looks great! I like that you can do "black" chrome with it too (or, I guess, will be doing it until you master it) because that's an effect I've been wanting to do for a while but couldn't figure out a convincing way. If anyone does find it, please let us know!
Thanks for the video link, too, that explained it really well. It's interesting how much a better understanding you get when you see it, even if you read a good description. Those modeling videos are great - I wish they were translated! I'm really curious about the painting effects he did later, around 8m; why was he holding his finger over his airbrush's tip and spraying bubbles into the cup??
