Keep on Building!
Thanks to everyone who has made the playpen a success during the past several days! We're going to keep the area open through the music portion of the conference, so you (and your kids) can keep right on playing.
All sorts of cool projects and structures are lining the windowsills around the playpen area, and a lot fo them have been very well documented, so don't be afraid to take some apart and start building anew. Keep those photos coming!
