I never spent a lot of time using Lisa, but I got several opportunities to kick the tires as a Mac repair tech in the early 90s. I even fixed a Lisa or two, and converted one to a "Mac XL". You've captured the UI really nicely, and it was fun to click around. Good job!
I'm really happy you enjoyed it! The Lisa's a really cool machine; definitely easier to work with and service than some of Apple's other designs...
