"LayerOne is a security conference which focuses on a broad range of subjects such as networking, hardware, cryptography, and more. Within the conference, we will be hosting the LayerOne Demoparty. The purpose of this event is to allow hardware and software enthusiasts to create demos and show them off! The rules are fairly simple, draw some pixels on the screen and/or play us some music! The more impressive the pixels and/or music, the more cheering you'll receive from our wonderful audience."
