John, I found a website: www.ropek.net which shows the piece in more detail
with an explanation. It shows the lines on the floor to be hourlines. In that
case, it would appear that the arches aren't noting the sun's path, but are
facing west instead. The top arch has an indicator at the top which crosses
the hourlines. I take it that you've only seen it by pictures, too. I did see
a link to email the artist on one website, but not his email address. sasch

Can any of you figure out how this strange sundial
functions? It is called “Sun Shell”.
It is located at 15151 E. Alameda Parkway at
the Aurora Municipal Center in Aurora Colorado USA. It was made by an artist
named Rafe Ropek. But who deliniated it I wonder? It is not in the
NASS Registry.
Here are three excellent photos of it:
