Description
I know the effect makes more sense on the iPhone Duo because of the dual screen, but I wanted something similar on the MacBook: the lid looks like a portal to the real screen. The only app I found that does this charges for it, so it felt like a good thing to ask Astra to build, and I made it OSS. Visual improvements or feature ideas are welcome.

Feature requests: Improve cross-browser compatibility (Firefox support)
