"I test it with sound at 1:50

I bought this weird box many years ago, but I have never really found out what it is. I don't know why. It turned out to be an unpleasant noisemaker that is apparently build for use in cars. I don't know why anybody would want such a develish device, but on the other hand I don't understand the urge to have 'fuzzy dices' either.

The music is just me carbonaraing on my Elka X-1000 for little over 1½ minute."
