A couple of months ago Microsoft unveiled a futuristic computer (code-named Milan) that uses wireless auto sync and touchscreen technology to allow users and devices to interact with files and applications using a flat, table-top screen.

Apple hasn't yet responded with a nicer-looking table, but its technology is powering the perfect accompaniment - an interactive table and chairs that change colour to match the hue of whatever has been placed on the sensitive table-top.

On display at the Siggraph show, the Japanese Fuwapica furniture uses sensors embedded in the table-top to determine the colour of items placed on it. The furniture then changes to match that colour.

These sensors also work out the weight of the sitter, with fatties creating darker shades.

It all seems fairly pointless but fun anyway, so it's appropriate that it's all powered by a Mac buried in the table that sends wireless messages to the chairs, which project light through their translucent shells to match the colour of the object on the table top.
