My wife grew up in the home we live in now, as we bought it after the last renters trashed the place. It has been her dream since she was a little girl to light up this big tree:


This is a typical bull pine tree that has split a few feet off the ground into multiple trunks running up 45' higher. This complicates things greatly up top for some sort of attachment point up there.

My initial thoughts had been some sort of aluminum ring with channels in it for the attachment of pulleys in about a 270 degree arrangement. Those pulleys would have a sheathed steel cable and not allow the cable to be able to jump the pulley.
On the end of the cable would be a 5 to 10'b fishing weight that could fall down along the trunk of the tree. It might take a few tugs, but a lead ball weight would eventually make it's way down. The other end of the cable would go basically to the bottom of the canopy on the outside.
The problem with that arrangement is possibly loosing control of a cable and it being too far up the tree to retrieve. So some sort of stop has to be on the table as the maximum amount that can fall through, or to make the cable a loop so it can always be retrieved.
However that split may make that not work.
I had figured that if I could get 4 strands or so on a pulley, then I could attach a guide wire and pull them out away from the tree branches as they are hoisted up or lowered down.
Anyways, crazy ideas welcome, I will have access to a bucket truck one time to get the basics in place and need to figure out how to do it, and what to light it with.
Initially thinking about a dozen pixabulbs and another dozen dumb led strands in single colors. The pixabulbs controlled from an ssc with 50 nodes and about 50' long at the edge of the canopy. The regular LED's by just a lynx radiating out from the tree trunks. That I hoped would give at least a little effect to the tree for the first year of lighting it and then if I get the mechanics proper at the top, I can add on a few more strands every year.

Thoughts, well wishes? Crazy ideas that you saw someone else try?
