Excellent! I just wanted to pop and warn any control freaks like myself not to be tempted to change your code. For example, i always find the prepended ampersand when calling a sub to be ... ugly. You can imagine my surprise when i changed &p and &l to p() and l() respectively. ;)

Also, this:

@_ = map { 0 } (1..$w*$h);

Can be written more efficiently as:

@_ = (0) x ($w*$h);

but that's just a minor nitpick. mayaTheCat++
