Where would you use a music visualizer?

I’m the maker of LIQUIDWAVE, a music visualizer for Mac launching here on September 19.

You can keep the visuals on your desktop, or connect a projector and fill your living room with them while listening to records. Microphone input lets the visuals react to music playing in the room.

Here’s a short demo: https://youtu.be/tTpFi87OXTU

Would you use something like this at your desk, in your living room, or somewhere else?
