Interesting. I've seen modeled wrecks and vehicle-shaped/-sized craters, before, but never etched acrylic profiles.
For anyone interested in custom work, I don't know what their current queue looks like, but Warmill (right here on Dakka) has been cranking out some pretty cool stuff in both wood and acrylic - might be worth scoping out his
lengthy thread (skip ahead for the sexier stuff) and shooting an email/
PM.
