Good design is about discovering the mind-blowingly obvious and reinventing the commonplace in indisposable ways.
A Circular PoolThe DGI in downtown Copenhagen reinvents the modern swimming pool. Don't swim short laps, turning head over feet to avoid smacking your head - swim graceful circles!
Nearby, a deep pool surrounded by diving platforms. Climb up two stories and plunge in feet first, or halfway there and dive in deep. Bounce from stairs onto a trampoline into the water. Scamper up a rockclimbing wall towards a diving platform, fail to make it, and fall into the water!
Add a thorough, awesome sauna, and this is the kind of exercise palace that leads me to hope I might some day develop a routine fitness program. Routine would be the worst word tho - the chance to play around diving adds much play to the ordinary repetative workout. Whee!
