It would be nice if there were a plugin were you can shape the window of your app/game. <font color="green">Like the window's shape must be a circle</font>
I have created a very simple Example:
<font color="blue">It is a Block that you can move on your desktop with your arrow keys, it stops if it collide with your taskbar</font>
How to use:<font color="blue">Shift = The Block Jump</font>
<font color="blue">Arrow keys = The Block move on the taskbar</font>
