I made these pendants (45mm across at the widest point along the top edge) as gifts to give to people at Burning Man. I liked the idea of using an "impossible" shape and turning it into a tangible object... hence the name I'm-possible. They were lasercut from 3mm ply. Each piece was made in one pass of the machine, by working out, testing and layering up different settings for the cutting and engraving file paths. I was very pleased with the end product and the subtle gradients & tapering of the engraving added additional depth and a little more finesse to the design.
