Hi Daniel, This is neat, I agree, but one still wonders why?
1) Maybe some corp. will use it for their logo with genetically
modified carp doing Busby Berkeley designs in the water for a
30-second TV spot?
2) Posh hotels using it in a device with freezer for monogrammed
ice-cubes?
3) Temperature readings on the water's surface in a hot-tub?

The possibilities boggle...

Meanwhile we're still trying to get funds for printing books in
African languages for school kids there...
