I think a cool idea for a beginners tutorial for game dev would be remaking the game Simon, its simple to do , i have done it in actionscript(flash) a couple years ago ,i am an obj-c newborn i am not familiar with the syntax.. its just so different than java or AS, which is what i know, but anyways i would like to know if there is an open source of it already or some type of decompiler i could use to pick apart an app to see how the concepts are applied in a diff evironment?

, it would make learning obj c so much easier
