Echolocation walker tech demo

Just a quick tech demo inspired by an article about dolphin echolocation being more similar to touch than to sight. Headphones are recommended but not necessary.  Gamepad controller is much recommended but not necessary.

Lower clicks are for walls. Higher clicks are for target.
Faster clicks means object is nearer.

Target will also make a sound if in range. Louder if you have a clear line.

There's also a compass ping. Louder and centered means you're facing north. The target is generally north.

When you hit the target, you'll hear a ding and the target will disappear. Then that's that. You need to reset the page if you want to try again.

There are no real visuals but the blue bars may be of help to some.

Comments most welcome.

Circle will toggle the compass on/off. Triangle will send a single ping. Rumble is enabled for when you bump a wall.
