One example is the appropriately named Involving Systems. Three modules are set up in a room, each featuring various lit buttons and dials. Module 3 is outfitted with a record player, and anyone can snap up samples and play with them. All in all, it's something like an interactive installation. It really works for dancing, too.
People can really use it at parties, making their own music.
This participatory ideal pops up all over the map. Musicians such as Oval and Brian Eno have been experimenting with software that allows listeners to set their own parameters and either let the customized tune go where it will or actively interfere. And Sony Music has just released Phosphoric Brain Massage, a unique offering from the Austrian artists Station Rose, who view their music, graphics, animation, even their hosting of the Frankfurt conference at Electric Minds as a singular, ongoing artistic project. The overriding idea is to dissolve the artistic ego and engage the people. And this was the same with techno music in the beginning.
