Could also just rent a turn table type device similar to a mirror ball motor and mount a
Fresnel on it. All a question of budget
etc. Even read here or somewhere else about someone that did a turn table as in LP turn table to do the light.
Moving light would probably be easier unless you found a source that has such a thing for rent economically. Some of the larger lighting companies will probably have them with even power transfer to the spinner to run the fixture. Bash should be local to him.
Otherwise given it's Zac, he should shoot for a Coemar Super
Cyc and make best use with some 250w wash light he gets. Might hate the Coemar fixtures, but my what a wash of light it would give. In fact given the gymauditorium, it would be more a show centered around the Super Cyc than anything else. Zac I'm sure would take great pride in that as it would be kind of fun to center a show around and take the entire crew to install.
By the way, I have not been back to the airport since about 98 when I was helping to set up the Triathalon on airport grounds. Oh, wait a minute, it's a private airport and normal people can't get onto the grounds, yea that's it, and a little plane is going to take out the Sears tower. Wonder how the Air and Water Show has been getting along without also?
Still, how are the jungle gyms and picnic areas going on the old runway? Lots of shade trees installed yet, or did the city suddenly run out of money and put the project except for midnight X's dug into the runway on hold? You know the real reason for this was it's less than a mile from the Mayor's condo and directly about in line of sight with his view of the lake don't you? He lives just off Roosevelt and Indiana if I remember the street right in that condo area. Used to drive golf carts and fork trucks on the street past the police parked outside the condo frequently. Only in Chicago...
