I was motivated to create a Smalltalk system that had only what it needed to start and extend itself, so that newcomers could install and run the system quickly and easily.

I've developed a minimal system which can install itself from a single web page visit. It's a webpage that, when visited, downloads an installer program and runs it. The installer program downloads a snapshot and virtual machine, then decompresses and runs the virtual machine. The virtual machine decompresses and loads the snapshot, and the snapshot updates itself. The installer is 60KB, the virtual machine is 125KB, and the snapshot is 91KB, for a total of 276KB (or about ten seconds of download time with a typical broadband connection).
