Japanese color chooser (nipponcolors.com)

The munsell effect makes very impressive use of 3D CSS. (At least in Safari.)

In Opera 11.01, I can only pick one color, then the squares stop having any mouseover or onclick effect.

What is this for?

for people having issues, this thing requires Safari

Clicking each color changes the background color to match and displays the Japanese word in kanji and more importantly, roman characters.
