Hi  
so I have a grid of 5\*5 that I have filled with random colours with each individual mouseClick.  
How do I reset the grid back to white with the next mouseClick? Also how do I use a timer so that the resetting animation of each square can be clearly seen. I don’t know how to execute this.  
Cheers
