Need to create a flash application that will do the following:

Allow user to select house color.
Allow user to select roof tile type.
Allow to select percentage of colors (like 20% black, 40%red, etc...), predefined colors
The application will scatter the tile colors on a roof randomly to give an example of how it will look.

All tile types/colors will be given as photographs in the size/angle needed for the flash.
Also there will be a static picture of the house, should only paint one part of it when user chooses to change color of house.

something like this:

just that all tiles should be placed automatically after user defined percentage.
Also take in mind that not all tile types have spaces between them and need to be a way that they will be connected graphically.

can use ready flash templates if they will satisfy the needs.
