Cute tiny little lizards, I've been building up a stock of them for larger tessellations to come tomorrow.

These are lizards taken from the Escher drawing . Each one is cut separately and square to the grain so that when they are all tessellated back together then they all reflect the light slightly differently which is a nice effect. ( svg here )

I modified the design to exclude the external ring and also tried to get a gap between the 'seeds'. Better but I can still do better.

This is my first attempt at a wooden log coaster, I cut a disk from a suitable sized log and attempted to engrave it with a sunflower style motif, it is ok but I'm sure it could be better.

I went over to see a guy called Chris at the e Xtrodinary Laser Company last week. He just bought a laser too and that laser company recommended making some of these nubbins to keep the work lifted off the honeycomb. It's a good idea now stolen by me :) suitable for the LS3020 honeycomb bed ( svg here ). (edit, 20th Jan) These nubbins are also doubling up on the underside of the honeycomb as a secure way of lifting the honeycomb off the bed so the vapour isn't trapped in the comb.

The Cardan gear is a clever mechanism for converting rotary motion into linear motion, it comes in 2 flavours (see links), in this variety the end of the arm travels with straight line motion. ( svg here ) http://robives.com/mechanisms/cardan http://www.mekanizmalar.com/cardan_gear.html

What good is a mini digger without a sandpit to play in ( svg here ). Unfortunately I haven't found the sand to go in it yet.
