Tom, i was reading what they are doing with photography and the medical world. i'll see if i can find that article. no wait...i mailed that magazine to my brother after i finished reading it. anyway, the article was about cameras that you SWALLOW. It takes pictures of your gastrointestinal tract i believe. the camera was like teeeny tiny. oh man...i'll have to see if i can find something on the web about it in the morning. i'm so sleepy, Tom. night. :)
