Meet ViVi: a LED light controller that lets you put on complex light shows in sync with your music. It has a portable, wearable design and does not require complex programming. ViVi offers automatic volume tracking. You also get app control and non-proprietary light support.
ViVi does not require any soldering. It has a 5V power input. The custom app lets you adjust your lights easily. More information is available on Kickstarter.
