Help me build a game which will rewire your left-righ hemispheres connection

The Bioneer - Become Ambidexterous - Increase Creativity http://www.thebioneer.com/become-ambidextrous-increase-creativity/) Left hand is controlled by right hemisphere, right hand is controlled by left. The part of the brain connecting them together is Corpus Callosum. MRI/EEG brain scans revealed the longer person spent time playing particular musical instrument, the bigger C. Callosum become (up to 15% compared to normal peple in one study). It looks like that A. Einstein has C. Callosum extraordinary big and it made him extremely creative - he was a leftie and played violin from age 4. All lefties are considered more creative, and I think it is because normal society forces them to use their right hand which causes as a side effect ambidexterity.

OK, not many people are creative geniuses, jugglers, self taught pianists or posses a handpan. But many people do have computers :-) Why we dont have games which uses two mouses?

Game Ideas to program:

1) Pong (Table tennis game) - simply using different hand for each paddle 2) Catcher - Catch the balls fired on the screen but each time use different hand 3) Patterns - My favourite inspired by handpan playing and due to all possible variations. Simply draw presented shape periodically with one hand - it can be segment, triangle, rectangle, star.. determined by peaks (joints) and on each joint player should click the mouse. So even if you have to do this with only your opposite to dominant hand it can be challenging, now assume adding also other hand and draw different object (or catch randomly appearing dots). It all can be timed/controlled by metronome. I love it because there is unlimited possibilities and it can be really quite challenging simple looking game and there are no borders how far a person can go..
