I'm already planning next years display and my major addition will be a mega tree. My question is on size, i'm toying with a few designs anywhere between 4m and 9m tall. My current thought is for a 360 degree tree 9m from ground to top ring with the option of a star on top next year. 16 x 8m of ray's pixels at 100mm spacing attached to 2mm galvanised wire to a 2.5m ring at ground level. I'll program it as if it had 32 strings and just patch every second one in so I can easily double the strings later on. The base will be cemented in to the ground and a tilt over plate will attach the top section and allow one person to put it up in a few hours. I'm thinking size would be relative to the size of the yard it is in and we have a 1 acre property with a big front yard. There is also a bit of a dick measuring contest going on with the people up the road a little who are on top of a hill and their static tree can be seen from 5km away.
