I am working on an educative game for kids.
I was thinking about what kind of prize to give them to encourage spending more time/learning.
The idea I am going to try is : have a picture blurred or obstructed somehow. The more exercises the kid does - more parts of the picture are getting revealed. Also, the revealed area size might be bigger if the kid finishes the exercise faster..
So I have two questions for the creative folks here :
1. Do you think this is a good and encouraging prize ? ( kind of trying to play on their curiosity ... )
2. Can you think of a nice way/effect to reveal the parts of picture ? Things I've been thinking of are rather trivial : puzzle like parts getting revealed, the alpha/blur of the whole picture getting changed from total blurred/transparent to full-color picture, the stripes revealing ( like on those huge high-way changing signs ) ...
