Need help for teaser ad campaign for uni event?

My major is MIS, and we have a semester project that is basically conducting an event in college where we basically focus on technology. The name of the event is Entechtainment. There is also going to be an auction where we sell off stuff like old cellphones, iPod's etc. I desperately need help for a slogan or catch phrase that we can use to advertise the auction AND the event.
