I often tell my friends that I am too inventive for my own good. Here are some too inventive ideas from Xeno Freaks, Inc in Korea [via Suman Park via Cyflux]. These webpages are in Korean language, but pictures are sufficient to communicate the freaky ideas being presented.
Xeno Freaks ARS (Anus Recognition System)
Biometric authentication technology of a different kind. You can find more pictures at the ARS web page, but don't go there just before or after a meal.
Could be a brisk seller if it checked health-related problems as well. Probably not appropriate where there are many absent-minded professor types.
Xeno Freaks Self-Rechargeable Mobile Phone
Every time you dial, you are charging your phone's battery. I love rotary phones!
