I don't know if there will be another Scirra competition as soon as this one finishes, but there are loads of competitions all the time over the internet.
Ludum dare is quite cyclic for example.
There are also the monthly Mozilla's devderby (not specificaly games, but I believe C2 can be useful in the making of something neat quickly).
Those are only two examples out of dozens <img src="smileys/smiley4.gif" border="0" align="middle">
