So, I have just the time to make a draft : it's more a toy than a game, but on a big screen, with some friends and some beer it could be fun
I need to rework the display and use my "toy" as an application rather than an applet.
(you can sing yell or whistle, frequency needed to pop the bubble is given, and capture frequency is displayed on bottom left corner).
edit : it's ok for 4k without signing !http://forthx.free.fr/tmp/4k2014
I'm sorry if it does not work, i had no other idea than another flappy bird (with metal slug "machingun") but i'm not sure this is a good idea
