A little eToy challenge...

[Naala Brewer]

Hi Leo,

I love a challange!

Try this (I don't know if this is exactly what you are looking for but I 
tried it on a Squeak plugin image and it satisfies your criteria below):

"Bird look like holder's value at cursor
Holder's cursor increase by 1
Bird move towards sun
Bird's scaleFactor decrease by 1 / 200"


This code was done purely with the etoy tiles.

With my best,
Naala
