It arrived yesterday, and thus far the pandemonium has been incredible. It took its standard 60 minutes to map the living room / dining room / front hallway and, in the process, spook-out the cats. Watching it navigate around the furniture was like watching my CS 115 professor explain how we were going to write our first somewhat complex recursive method in java – finding a route through a maze. You know, something like:

public boolean solve (int row, int column) {
	boolean done = false;
	if (valid(row, column)) {
		grid[row][column] = 5;
		if (row == grid.length-1 && column == grid[0].length-1)
			done = true;
		else {
			done = solve(row+1, column);		// down
			if (!done)
				done = solve(row, column+1);	// right
			if (!done)
				done = solve(row-1, column);	// up
			if (!done)
				done = solve(row, column-1);	// left
		}
		if (done)
			grid[row][column] = 7;
	}
	return done;
}

Admittedly, I’m enjoying SyntaxHighlighter a bit too much. This particular model lets you set a schedule for when it should go about its business, which is very convenient since it means we can set it to terrorize the cats clean the house while we’re at work.
