The Ducati. (Once it is put together and running again.) Seriously, though? A watch face. Design a watch that makes the most of Klein Blue. Simplicity. Elegance. The color is the prominent feature, but the design the purity of the Yves Klein design ethos (the Unity) driving the functional aspects of the watch. Kinda like a more usable Movado, with the utility of markers, designed with the simple elegance of the Unity. Backed with Klein Blue. Shit. I might even WEAR that watch...
Ochs & Junior are already there. If I had a spare $15k I would totally rawk a klein blue Day Night. I need to talk to my buddy the gemcutter. I need to know more about doing ultrathin cabochons. After all, International Klein Blue is effectively ground lapis and lapis dials have been done.
Something similar is done in geology for ore microscropy. Dunno if it helps, but it's a well-documented procedure. EDIT: Just to save some time, here's an entire book.I need to know more about doing ultrathin cabochons.
