New laser cutter

My new laser cutter arrived at the start of last week, I feel a little guilty for not posting it sooner especially as I've been teasing it on Twitter all week but here it is, in all it's glory in a single post.

The photographers clearly liked them too and there are some amazing shots floating round out there.
