Do you mean the Self site at browser.russell.larrikin.org? If so it’s
mine not Jecel’s,
Ooops, sorry. :-)
and I made it to be a public facing browser only, so you can’t make
changes to the underlying image. It wouldn’t be hard to add simple editing in, but we’d then need to do some sort of sandboxing because otherwise every web user/robot could trash it.
It would be interesting to have a web version of Self, so everyone could "play" with it without installing anything. I don't know how difficult would be to allow editions in a sandbox per visitor, but it would be a really nice choice.
