I always thought there was a lot of charm in the OS and browser simulators made in Flash, and I don't know why. It's just amusing to see how what's going through people's minds is put into these emulations of existing things. Anyways, this is really nicely designed and I would like to see more, along with features like a home, back and forward buttons. It might be a challenge to program but it would add to the immersion and usability.
P.S. Is there a password to the Secret Wiki?
