I really enjoy Jerram's work--it's infinitely pettable. Been seeing a lot of science-related work lately, some in glass, some not. (If you haven't seen Julian Voss-Andrae's metal sculptures--he's a physicist who reproduces molecular structures on a huge scale--you should. They're amazing.

Here's macrobiology from a completely different perspective, for example: At the last meeting of the Oregon Glass Guild's Portland Chapter, we got a hands-on look at the work of John Sollinger, a biology professor and geneticist who has taught himself to make mosaics with BE and Uro glass on a float glass substrate.
His designs come from photos he takes on his field trips (mostly), and demonstrate aspects of plant growth patterns. If you get a chance to see his work in person, it's really amazing--some of the glass shards he uses are pinhead-sized. He took best-in-show at the Mosaics International, first time he entered a competition with his work.
