We hope you are having a happy Christmahannukwanzika. This post is for all of you out there who need the dreaded "guilt gift". You know who you are -- you received an unexpected gift from someone and now feel the need to get something for them in return. Here are four holiday "guilt gift" ideas with a techie twist from our friends at ThinkGeek.com. USB Plasma Ball - Remember the plasma balls that used to be sold in the mall at Spencer Gifts? Now, they have one that plugs into your computer. The perfect desk accessory for that eccentric friend.

USB Memory Watch - In addition to displaying the time, this watch helps you carry your valuable data with you at all times. With 2GB of capacity, it has more than ample storage.

USB Drink Warmer and Chiller - It's perfect and it's simple - a hotplate powered by USB keeps your coffee warm. Flip a switch, and it can keep a cold drink cool. Great for bipolar caffeine addicts.

Driving LED Emoticon - The Driving LED Emoticon is a battery powered, wirelessly controlled message sign that can be attached to the rear window of your car via the included suction cup. It can display any one of five different messages - smiling face, frowning face, "Thanks", "Back Off" and "Idiot". Isn't it great that technology allows us to communicate more clearly than finger gestures?
