Alice/Arisu Keyboard

The Alice (or Arisu) layout is an ergonomic layout where the innermost four columns on each hand have been split and separated and angled inwards. The remaining keys have a slight symmetric stagger. Most keyboards are a flat single piece.
Though these two keyboard styles are extremely similar, and Arisu is actually the Japanese translation of Alice, these two keyboard designs are not the same. The biggest difference is that an Arisu keyboard has an arrow cluster, while Alice keyboards do not.
