Measuring my brain waves would be rather sad and not fun and hilarious. On second thought maybe!

The NeuroSky MindWave turns your computer into a private tutor. The headset takes decades of laboratory EEG technology research and puts it in your hands. Experts agree that your brain needs to be exercised just as much as your body. Strap on the headset and the MindWave Education system will monitor the attention level of students as they interact with math, memory, and pattern recognition applications. Ten apps are included, some educational and kid-friendly and others are seriously fun for all ages. Developmental tools allow you to write your own programs to interact with the Mindwave, too.

- Cheap ART you can own

Pretty neat idea for a wedding ring. This artist records parts of the wedding ceremony (like the part "Yes, I do!") and lasers a cut out of the sound wave.
