G33k Xmas is a roughly-annual gathering of friends who are obsessed with technology and art. We get together and offer up our extra tech to anyone who shows up, and take home whatever we find useful. The conversation and curiosity around the different items makes this an amazing night of g33k fun.
Swapping technology, versus buying something new, allows us to try many different technologies out, hear about new ones (who knew vector displays can be hacked). It encourages the reuse and repurposing, instead of recycling or purchasing of technology.
