Theodore Gray now has a whole range of the most beautiful Periodic Table posters for sale. Gray is well known for his wooden Periodic Table, erm, table.
But what caught my eye delving a bit deeper are his interactive displays. Each element has a touch sensor which brings up information about the element. Basic interactivity I suppose (it’s not like you can irradiate your friends or anything), but a real lesson in beautiful craftsmanship for a display.
(Thanks to Lot 49 for the poster link).
