Idea 1: God from Monty Python and the Holy Grail as a soldered stained glass mural, with glowing components and sound bites from the movie that are motion activated.
Idea 2: Lunisolar Calendar in the form of planetary models. Three led orbs will travel in their relative positions from each other to represent the time of year.
Idea 3: Similar to the second idea, except instead of orbs, it will be shadows across a projected sun to keep track of the time of year on a lunisolar calendar.
