My students have been laser cutting and engraving various materials in hopes that it might expand the kinds of things that we usually think about being laser cut. A couple weeks ago, Kaivahn and I noticed something interesting while laser engraving a leaf. The wood that we had the leaf taped to, was getting engraved since we had the power set a bit too high. We examined the wood and found that in the wood was embossed similar to how we emboss metal with a rolling mill. The veins of the leaf threw the focus off and cause the vein to be raised in the wood beneath. Interesting effect...
