I wanted to comment on the blog but the comment link seems broken.
This is basically the algorithm I use however instead of using a recursive call I have a variable that keeps track of the current position. When I run in to a dead end and need to backtrack I mark the cell with a special backtrack flag and find the only neighboring cell that I can move back to that does not have the backtrack flag.
