[etoys-dev] Touch Interface thoughts

[Bert Freudenberg]

Yes, in the paper they say it was "heavily inspired by Kodu".

Btw, I just made a new build of the iPad app (the old one expired, I had to renew my developer license first):

Also wrote a little explanation there. Installation has become a lot easier, plus you can even change your image for experimenting.

I have wondered if it would be a good idea to have sets of tiles be enlarged when the cursor is any place inside that area. If the cursor moved to another category of tiles, the first category would shrink back to the size it is now and the new area would increase to the larger size.
