This has got to be the coolest idea for a clock. The light panes act as the digits in the same way a small watch or clock radio would. The innovation here is simply the scale of application. Everyone expects the time of day to be presented in a particular scale, normally small. When this is blown way out of proportion and used to dominate a space, the result is a very intriguing design composition.

I absolutely love Richard Meier's work, this gallery space in particular. The way the light casts on the slats of the ceiling looks incredible. Most art galleries are very boring and washed. This adds a little bit of understated flair to a normally bland environment.
This picture makes me imagine if there were several panes of glass layered at a particular offset. Each having some sort of etching on it. If you light the panes from the sides, and conceal the edges of the glass, as well as the light source, what would remain to be visible is a 3D image that appears to float in space. I have seen this done with shop cash wraps and such. It could be interesting.

Not a lighting piece, but a very interesting play on shadows. With some light features incorporated either behind the lattice, or shining on it such as pictured here, it would provide a very strong architectural and design statement; a very powerful vehicle for concept depending on the pattern of lattice or lighting used.
