A friend passed along an interesting article on a few techies that are inviting anyone who can check in on Foursquare to their place. The have the Door - an innovation that opens the door when you check in. I took a look at the website for to see all of the other innovations as well at apartm.net - pretty neat stuff, all resulting from a bunch of people working in the same room with one another.
After two weeks in the Beehive in December, I am increasingly looking for a way to get to work innovating with some of the bright people I worked near. It just reinforced for me that being surrounded by bright and aspiring individuals is the best motivation for coming up with cool stuff to work on.
