Dwell Magazine's daily blog featured these very cool sculptural stairs from Swedish firm Taf. A ladder was first placed in the spot to set the placement then the zig-zag chunks of wood were placed to create the stair variation.
Although really beautiful to look at, we're not so sure it would work in practice. We have had experiences with even just a narrow step with our big ol' feet and the combination wasn't such a good mixture. But...bravo for thinking outside the box!
