Of course! It's been a while since I've done much javascript and I had forgotten about setTimeout. And your do/while loop in the R() function is much cleaner than my hack. :)

One thing I noticed is that you're setting the timeout value to 350-s.length*5. As the grid is 16x16, the maximum snake length will be 256. Multiplying the length by 5 will soon make the game humanly unplayable somewhere around a length of 60.

Re-reading my comment, it's ambiguous what the "of course" refers to. What I meant: of course I should have used setTimeout rather than the lamer setInterval/clearInterval method.
