Often times, this is what I see when I hear music. It's a hell of a thing to live with from day to day.

Synesthesia is awesome. I've never experienced it when it wasn't pharmaceutically enhanced.

Yeah, it can be cool at times. Trouble is, I see colors everywhere I go. Store, mall, elevator, you name it. Starts to get a bit of a pain in the ass after a while. However, I must admit that in my younger years, when I did do a large amount of LSD, it was super fun. Now days, not so much.
