For the record:
In addition to our blog, we have ongoing emails. The initial email might be about scheduling a meeting, and then grow to include questions and research about, well, anything. Here’s an example, after I told Michael I wanted to meet in the city so I could buy a projector, maybe at B&H.
Wendy, Here’s about an hours worth of searching. I stumbled onto pico pocket projectors. Let me know if you want me to back out to “normal” projectors and see about low cost. My view is that the small projectors could be a good prototyping tool for you in the same way that the photo frames and the XActi camera are. You may even be able to connect your XActi to one of these. Michael(The email had an attached PDF)
