Geometric Music is a free app (download here, or fiddle online) that takes sounds recorded from your environment and assigns them on-screen geometric shapes. Manipulating the shapes and arranging them relative to one another allows the user to build looping, layered musical pieces.

There's an old adage about humor: Explaining a joke is like dissecting a frog. Nobody's that interested, and the frog dies. It turns out that some people really are that interested. Here's a quick experiment that tries to figure out, scientifically speaking, which sort of slapstick is funnier.

In the big wide world of mental disorders, synesthesia is probably one of the most interesting and least harmful. It's like a sensory remix. But what's it really like? Alex from Bite Sci-Zed, who "suffers" from a flavor of the disorder where her numberals have very distinct colors, explains it. By the numbers. […

Unless you're a synesthete, you probably don't get very many opportunities to see music. But this 3D data visualization project, Portrait of the Ghost Drummer, by Polish designer Odaibe allows you to do exactly that.

No ideas? What about a passing train — has listening to one ever evoked a specific color in your mind?

An estimated 4% of the population have synesthesia, a condition where senses become confused.
