What desk would be complete without a USB Christmas tree this Yuletide? Standing 11Inches tall and USB powered, the illuminated needles phase red, blue, green and pink when plugged into your computer USB port. Better still, the tree comes complete with cut out decorations and tinsel to decorate the tree. The good thing about this tree is that the needles won’t fall off and it doesn’t require an enormous effort to put up or pack away, for added effect there’s a wooden looking pot for it to sit in. Now It’s just a matter of finding a spare USB port on your PC or notebook and plugging it in.
