I am in the initial planning stages for a LEGO build of Serra's Sanctum from Magic, The Gathering. Part of the description states:
Serra's Sanctum was a notable landmark of the plane, suspended somewhere in its infinite sky. The Sanctum was the dwelling place of the famed planeswalker herself. It was massive, taller than most structures on other planes. Powerful artifacts run through white mana and having white-related functions, such as the Cocoon, could be found here. At the top of the Sanctum was the aviary, where Serra could see the entire plane through many powerful lenses that kept an eye on her world. Only planeswalkers could comprehend all these images simultaneously. Leading down from the aviary through the rest of the Sanctum was a spiral staircase that ended at the base of the building. It was here that the main plaza was presumably located. The plaza contained a water fountain that reached five stories high, carved with skillfully rendered angelic effigies. On the fountain were also the words art, discourse, freedom, peace. These are the ideals that Serra herself sought after and wished to center her world around.
It's the 'powerful lenses' part that I could use a little help with. My current idea is to use Plate, Round 4 x 4 with 2 x 2 Hole with some transparent-clear plates backing it to make a mirror/lens look. Do you folks have any better ideas?
