$20 USB Memo Light... Absolutely Pointless

Here's another USB ambient light that reminds me of Philips LivingColors except the latter gives a total of 16 million different color combinations and casts colorful glows on your wall. The USB version however is different in that the supplied marker allows you write memos on contour base while its ambient lighting changes color constantly to remind you of the message written on the surface. The other end of the pen allows you wipe the message off when needed. Practically speaking, this is still pretty pointless even if you consider this as an offbeat gadget and the $20 price tag.
