Masquerade

In the video I said I would put a link to the Maze, but I couldn't find a link to a website that a) looked like it had been constructed this side of the year 2000 and b) didn't contain spoilers. So, briefly, it is called the Dragonfly Maze and the goal is to find the dragonfly. However, simply getting to the centre isn't enough, along the way there is a rebus to solve (a say what you see puzzle) which gives you instructions for what to do when you get to the centre.

Also here's a picture of the Wishing Fish Clock which I mentioned:
