Fun-loving hackers and improbable tech-art: what a match made in heaven! HOPE is probably my top conference that I've never been to (I almost made it in 1999 but the flight was cancelled!). I continue to miss it every year, despite my best efforts (it usually overlaps my birthday, which is family time, for obvious reasons!), but I vow to go someday.
I mean, just have a look at that call for proposals: games to be played by thousands of hackers over three floors of a massive hotel; midnight to 9AM sessions; hardware hacking village... Talk about nerdvana.
Call for Projects and Tech Art (Thanks, aestetix!)
