If you are looking for a unique gift that contributes to a great cause, check out Cosanti. Cosanti is the studio that helps to support Arcosanti. Arcosanti is an architectural vision that incorporates the surroundings in an eco-friendly way. The bells are world renown, and are great looking.
Cosanti can be visited as well, and it is a unique piece of architecture as well, but on a small scale. The tours are self guided, and if you are fortunate, you can see artists at work making bells and tiles and other cool things. I highly suggest it if you are even just looking for something to do for an hour.
