"Here is one I ate earlier"

One interaction I really wanted to have in Five Trees Forest was for two players to meet and for their sprites to hop between phones.

The Nokia 6131 didn't seem to be able to do that (without writing an application for the phones, which we didn't have the time or cash for), and the solution we devised of sticking chips on the back of the phones didn't work well enough to risk.

So instead I wrote some enchanted food into the storyline, and players meet to exchange chocolate bars with sprites trapped inside.

As it turns out, this seems to fit very nicely with the fairy story, Alice in Wonderland feel I've been trying to create.

And if you get a bit peckish during research and development...
