If you want to find out what a Lisp Machine was like just run an emulator for either the MIT or TI ones on your desktop. Both are still being worked on, it wouldn't help their development to have extra translation stages into javascript. Any OpenGenera emulation in a browser would need to download a disk image containing all their commercial software, I can't see them wanting to put this on the web.
There are several Mac emulators that can run on desktop machines, the advantage of this new one to me is that you can package up a snapshot of a particular System version and the software that would have been used with it, I think we need to preserve key stages of computer development for the future.
