Its how people perceive things. I hear it all the time, "it's just some flashy lights". I don't expect people to know how much these things cost, much like I would have know idea how much it costs to design and a produce a car for instance. I was merely stating that sometimes the simplest looking effects cost the most to achieve.
Sometimes this is down to sheer scale - projecting an image onto a wall in my house costs pocket money but projecting that same image on a Disney castle costs thousands and thousands. Its not just what the audience see though. We pay for kit that is reliable, user friendly, serviceable, has good manufacturer support and above all does the job we need it to do.
It's a constant battle we have with people that write the cheques in the industry. "We want to light this building for an event. How much?". Start with the lights and add in rigging, power, data, control, designer fees, production crew fees, freight, insurance, running supplies and consumables. Soon something that looks cheap and easy becomes something that is difficult and expensive.
Anyway enough of me taking this off topic
I like the look of this, although these things never look anywhere near as good on video as they do in person. I've seen a few of the Disney spectaculars and am always impressed from both a technical and design standpoint as well as entertainment and spectacle. World of Color was incredible and this has a lot of scaled down elements (technically speaking) from that show, so I'm sure I'd enjoy it if I get to see it.
Disney refer to things like this as a "Kiss Goodnight". The idea being that even if you've had a mediocre day in the park they can wow you with something right before you leave. You leave on a high and are more likely to go home with a good vibe about the day, buy merchandise on the way out and return to park again. Just like most things Disney its very very clever.
