Thanks to my colleague Steve for suggesting this video presentation on learning spaces. Creating Innovative Learning Environments, presented by James Jorstad of the University of Wisconsin-La Crosse, is a 50 minute video full of ideas for learning spaces. Early on Jorstad shows examples of older classrooms crammed with technology--I'm sure you know what I mean--and describes how effective remodels or starting from scratch can yield spaces with "translucent technology." Basically this is a technology-rich environment where the equipment does not dominate and overwhelm the space.
In the presentation, he shows a number of successful real-world examples of lighting, projection, digital signage, displays, furniture, space flow design, tablet PC application, and more, with many from information commons spaces. You could get some great ideas here.
