Every couple of weeks I like to check into Jan Chipchase's latest travels. He's constantly moving around the world noticing little things, like how we noted our world with little messages using technology. On his blog Future Perfect he posted this nice find in Finland.

Key ring board for Helsinki's Yrjonkatu swimming pool and sauna includes a minature clocks to mark the entry time for each pool goer - anyone staying longer than the one and half hours is charged extra. Or at least they were - the practice of limiting the customer time in the pool hasn't been used since the 90's. The board serves multiple purposes. The number of missing keyrings provides a visual snapshot of how many people are currently in the building. And because each key relates to a specific locker it is possible for the attendant to 'partner up' pool goers to have neighbouring lockers, increasing the likelyhood of social interaction or in the case of males on the prowl, something more. Unlikely? On men only night? Yeah right.

I like the way it serves as a dashboard to the entire spa. I bet it does not last another three years before it is replaced by the standard PC screen.
