javascript php mysql app matching game.
Given a list of images and categories, you match them up for the ones that best go together.
eg:
category: food group
images: apples, steak, pears, carrots, chicken, and lettuce
The player would select apples/pears steak/chicken and carrots/lettuce.
You'll need to write javascript to dynamically match up the pictures as well as mysql code to store the matchings in the database.
Finally, there will need to be a page so you can see how the community has matched up the pictures.
