Game Name: Shellshock Live
This seems like an easy program that can be made. Right now some people use paper ruler to do this trick but it seems easy for an coder to make this into an actual program.
This video explains the game and how its done using paper ruler.
This experimental video shows the custom made program using C# in action:
Same video as above except now with Wind.
Unfortunately that program was made for experimental only and author is not releasing the source code. So hoping some coder here would be able to make this program.
