When I need to relax there are few things more rewarding than melting things with a heat gun.
Today I was goofing off with a spare pool noodle and tried slashing it across it's width with a razor knife before gently melting the surface. The result was a really interesting ridged texture interspersed with bubbly gaps. Here are a couple of shots I squeezed off before my camera decided to call it quits. The piece is about 13" long and roughly 2 inches in diameter.
It's a really bizarre organic effect, but I'm not quite sure what it would be good for at this point. If I was still into tabletop miniatures this would be ideal for some quick and easy Tyranid-syle terrain pieces. With a nice three tone paintjob and some strands of clear epoxy it would have an awesome, gooey appearance.
It would be great for some kind of tentacle or tendril, but I need to figure out how to taper the effect along the length of the noodle. The one I was using had a hole running through the middle, so melting it down to a point wasn't possible. If I can get my hands on some solid pool noodles without a hole I think the technique has some real possibilities.
