from the page: "Unfortunately, we're not cool enough to run on your OS yet. We really wish we had a version of Photosynth that worked cross platform, but for now it only runs on Windows.
Trust us, as soon as we have a Mac version ready, it will be up and available on our site."
i just built a joule thief on a breadboard... it works! :) but remind me not to buy parts from radio shack; their packaging materials for the transistors have the wrong callouts for E B C :(
