Bending plastic for fun and use

I ran across this interesting how-to video today. Having a pile of scrap Lexan, my ears perked up. Making covers for keyers and other projects interests me, as well as short stands to support a ham radio transceiver while leaving room for a Morse paddle or notepad beneath it. Now, I just have to find an old hair dryer and some plaster of Paris to try it out.
