Bathroom advertising is big, but now you can urinate on the advertisement and it reveals the ad. That's the heat activated urinal billboard in a nut shell. It's interactive urinal advertising at its best.

The IsoOceania Product notes, "The world of "Interactive" Urinal Advertising is endless... HAUB (Heat Activated Urinal Billboards) has taken heat sensitive ink technology to a new level. This innovative medium combines high definition color graphics, hidden by "disappearing ink" delivering an interactive message to a captive audience... A perfect strategy to get your message across."

Touche... I guess the only question remaining is whether or not you would want someone p*ssing on your brand.
