Thanks Mr Dang,
ON CLICKING SOLUTION
if there is not such On Mouse Over then click in would be the option, if you could provide some hints, it would be great.
ON YOUR CAN EXAMPLE
I saw what you did with the cat ant it is great...
What I am doing is a color wheel (https://goo.gl/fr9JEd) so green, red and blue are 3 diferent songs, if click on any of those colors, then the corresponding song plays. These 3 colors mix in between and then play those both songs altogether.
IDEA 1: I was thinking that for my case, if I could detect where the user is looking at the screen and then play the song, some devices can detect if you are looking at the screen to keep it on.
IDEA 2: what about if I use gyroscope of the device and try to emulate a bubble level (https://goo.gl/BcAYuT)
sorry if above ideas are to crazy but your example inspired me.
Thanks
Omar
