bravo

This took me a day. I saw the chalenge on the morning, felt thrilled by the idea it gave me, had the day off, started in the middle of the morning and ended it by the end of the afternoon. Perhaps 4 to 5 Hours of dedicated work.

How long did something like this take you?

Yeah, Thx all folks ^^

What a wonderful piece!

 WTF! This is so awesome! O_O Congratulations :D

 If this doesn't win.. People are stupid.

 This is gorgeous!!

 Wow! Great work :) Your piece is respecting the rules for sure! Congrats.

Nice work! It would be cool (but also a lot of work) if the knobs turned during the animation.

Very Clever.

Wow, great animation! Maybe a little slow, but great!

 Nice work. Would have loved the final image to stay a bit longer before being erased. Great use of color.

this is nice 

It's a bit slow. You should include non-animated version in the description for those who don't have time to watch the animation.

But yeah, I like this.
