I was wondering how hard can it be to play Rock Paper Scissors. Then I thought how hard can it be to create an app for that. So, I created an app for Android. Then I thought why not customize this for Sheldon Cooper by including Spock and Lizard and that's what I did.
You can download this app from Google Play at https://play.google.com/store/apps/details?id=com.asb.rockpaperscissors
