Christmas Wall – Good Use of Calendar Control in Sharepoint

An interesting development.

On clicking on the empty brick,a new form opens as a pop-up where he/she can fill the wishes.
Once filled the wish with name appears on the brick.
After all the bricks are completely filled next button will appear taking you to next wall.
On mouse over the message details are shown in a pop-up.

And do you believe?? Its a simple ASP.NET calendar control with some GUI changes a simple logic behind to show the multiple walls.
