Like anyone born in 1980, I have the proper reverence for anything that changes color with fluctuations in temperature. However, I'm not entirely sure I'd like an entire dinner party to see my butt print in all its hypercolor glory..
The new Thermochromic Table by Jay Watson, featured on Neatorama, is available for £850 (that's $1367.48). It is a massive table made in the UK of solid black oak, painted with thermochromic paint. Did you know there was such a thing? What would you paint? Would a table and seating be on your list?
I think the color-changing effect on the table might be extraordinary and ghostly. I'd especially like to see the rings left behind by glasses throughout the meal: I love the look of wine and coffee rings, and this would allow the rings to change and evolve and layer, without any damage to tabletop or linens. As dishes are passed around, they too would leave their shadow behind. I think my ideal use would be to load this table up with everything for a feast (Thanksgiving, say), let it all rest for a few moments, then remove everything and take an overhead photo. It could be very cool. Overall, I'd take the table, but would skip the bench. My butt print is nobody's business but my own.
