Pretty cool concept and a bold move from Disney putting this out there already. From what I saw of the preview, it is obviously pretty short. Originally I thought it might of been related to the flight time of the small drones but if the full show is supposed to be longer that would fix that issue. It's something that I have never seen done before so it's hard to not find it impressive. The tech being used is really fascinating and with some further tweaks, improvements and adjustments I think these drone shows could become an incredible experience. Right now I am just entertained by the fact there is 300 drones flying in sync in the sky with flashing lights.
The shapes were mostly disappointing as they don't seem clear enough to make out the objects they're trying to represent. The 3D tree was probably the best but is obviously a very simple example of what the drones could be capable of with some extensive show planning in the future. I could only make out the dove, the tree and I think one part near the end was supposed to be Santa's sleigh and his reindeer flying around? I'm not sure but considering this is a free event at DS, I think it's fantastic tech being used in a creative way that will only get better in time. Also, since this is obviously a test run for applications in the future, it only makes it even more exciting.
