TaDa! http://screencast.com/t/PUoBSbJn09M0

I have a small caterpillar!  Thank you so much Alan and Bert!  I really
enjoyed getting my feet wet in eToys.

So I started this journey because it looked like Cartoon Builder might be a
nice easy start to the world of creating stories.  Clearly eToys and Scratch
are more powerful but I had hoped Cartoon Builder would be less
overwhelming.

I've put a ticket in to not resize the characters unless they are too small
in Cartoon Builder, that might help a bit. I don't know if anyone is
maintaining Cartoon Builder but maybe it'll be an easy thing for someone
just getting started to do.

Overall, I haven't decided about Cartoon Builder yet.  Just using what it
has in it for images is not very interesting. I think the difficulty in
creating characters really raises the floor to using it creatively.

I also have thoughts on Paint and Browse but I think I'll write them in
different emails so that people who just skim the lists will know if they
are interested.

These are wonderful tutorials and point out the need for a wiki that links
to the activity pages of all the activities where people can put these sorts
of things.  eToys may be a special case, as its such a rich world and there
is already so much written.
