Result Blocking Glasses

There is nothing worse than haveing a game/race/downhill haggis racing tournament on tape and finding out the result before you get a chance to watch it.

Time and time again I will tape a F1 race, and then have something as random as walking past a department store while a newsflash is on the next day ruin it for me.

I propose a set of glasses that will go pure black when they detect you will see results, much like the ford prefect danger detection models.

Could be teamed up with earphones that play white noise when you might hear the results.
