Fed up of explaining the offside rule to your girlfriend? Just dump your iPhone in front of her face and run this proof of concept application by PSV Eindhoven.
Although I admire the innovation, the app isn’t actually that useful when you think about it. Offsides happen in a split second, are you going to spend the whole match looking at that red line? Linesmen are there for a reason.
The technology is by Layar.
