Does this sound readily fixable? If so, any pointers on where to look?
I expect we'll revisit this problem next week (this week is refinement
and new development).

Thanks! This is thanks to Om Yadav, our designer/illustrator. He only
had a couple of days to prepare the graphics for this demo but now
he's joined us full time so we're looking forward to lots of snazzy
new activities. We plan to grow both the programming and design groups
as soon as is practical.

Currently I'm working on refining the code from our demo activities so
that a non-programmer designer can rebuild them directly in Squeak.
High hopes :-)

Yep - this is how we ran it for the government demo.

That would be great! We'll get back to you with an icon tomorrow.

> And did you think about Journal integration and sharing, yet?

We haven't given this even the first thought yet. Ideas welcome :-)
