On the eve of Valentine's Day, here are some gift ideas that appeal to the geek at heart - everything from hand warmers to use while you type to jewellery made from recycled computer power buttons ... and if you happen to be a single girl this Valentine's day, the Girl's Guide to Dating a Geek might be able to give you a few tips for turning that around.

USB Tulip Hub

Instead of flowers this year, you could try this tulip USB hub! It features four USB high-speed ports, in the form of a colorful bunch of red flowers. Compatible with most USB plugs, for both Mac and Windows systems, at least this gift won't die after a few days. US$24 from Fredflare.

Beating Heart Pillow

Less Than Three Emoticon Ring

For the chat room romantic, this sterling silver ring should leave an impression. The "Less Than Three" unisex emoticon ring is a melding of traditional romance and millennium geek. Available in sizes 4 to 14, each ring is hand crafted and made with solid sterling silver. Prices start from US$55 from Etsy.

This t-shirt is obviously inspired by the popular social networking status update paradigm and should be shared in public. Available in four different colors and sizes (S, M, L, XL) from US$18.90 at Something Geeky.

Animal Screen Wipes

Here's a collection of screen wipes with a twist. These fun stuffed animals come with a lemon zest fragrance which is apparently good for mental clarity and focus.
