Technology Poster Board

I have been reading the MIT Technology Review e-mails on a regular basis in hopes of finding a great new technology that i find important enough to create a poster board on. So far, no such luck. There have been many interesting topics but unfortunately, the ones i find interesting i do not feel that i totally understand them. (not enough to create a poster board for them). Going to keep looking. Wish me luck! If anyone has ant good ideas let me know!
