This is a virtual heat pad. Use the mouse like you would your finger. I am not sure this will make it work online, mainly because of the 100 little squares that make it run. If it lags, download it. That's all. This pad unfortunately does not fill the whole screen. Why, you ask? Because I got sick of recopying the stupid little sensing squares, and the prospect of doing it 1000+ times just pissed me off. If anybody out there has the patience to complete the pad and fill the screen, go nuts. Just please give me credit.
