Re: [9fans] a simple chess board for plan9

Great work!

Maybe the mkfile could be improved a bit; I had to copy the images manually.

And since you're asking for comments on your C style ...
imho, most of it looks really good; maybe you could try to avoid deep
nesting of control structures.

if(cond1) {
	if(cond2) {
		...
	}
}

should be changed to

if(cond1 && cond2) {
	...
}

and

while(...) {
	if(cond) {
		...
	}
}

should be changed to

while(...) {
	if(!cond)
		continue;

	...
}
