I came across some nifty instructions for a real cheap light tent, one that can be made at the office out of regular scrap copier paper. So, I promptly put one together and took a photo with the droid of one of the trinkets I have scattered around my cube, the Coqui I received from a friend. Notice the seamless background!
Using the droid and PicSay Pro, I adjusted the exposure, added the word balloon, and voila! Check out the instructions for this light tent at http://tinyurl.com/yjob2gg.
