Emerald hourglass

Funny... the staff here at The Brick Bucket was chatting the other day about interesting uses for the Airjitzu capsule dome piece. In fact, our very own Dead Frog recently posted a MOC using that piece. But on this morning's browsing of Flickr I came across another nice usage: vitroleum used two of the domes to construct a neat hourglass. 

That's not the only instance of NPU here, either - check out the construction of the melted candle wax, and the little red flag used as a bookmark.
