We did it :)

There is an initial version of all Monticello packages that now constitute the Etoys image in our main repository at


If you load updates, it will first fetch changesets from the update stream, and then proceed to update packages from the repository. We will mostly just post new packages from now on. But if needed, we still have the update stream.

To get an Etoys image for development, either follow the procedure I outlined above (takes about 10 minutes here), or download an all-in-one zip (based on Etoys-To-Go) from here:


It's easier if you do not use save-as in this setup, only regular image save. The image name is mentioned explicitly in the VM settings.

New versions can be submitted to the "Etoys Inbox" by *anyone*, no registration required:


Of course, Etoys developers can commit to the main repository directly. If you want to have access, register on that server, and ping me so I add you to the right group.

We'll look at all contributions, though we need to be somewhat conservative. Remember this is used by kids worldwide, it's deployed on about a million machines, and more are to come [1]. Features are cool, but don't make the kids cry, mkay? ;)

Btw, if someone feels more comfortable using changesets, don't worry, you can still attach them to a ticket on our tracker at


Some other developer will then build Monticello packages and commit them.

So, the gates are open, let the contributions flow :)
