The Siafu (curiously named after terrifying army ants) is a concept laptop by designer Jonathan Lucas of Long Beach, California that would give people with impaired vision the tactile input they need to fully use a computer — from writing word documents to navigating the Internet.

Rather than relying on a display, the Siafu takes advantage of Magneclay, which is a synthesized oil-based material that takes on different shapes as it responds to electrical fields. In this way Magneclay can mirror the front page of Google, pictured above, or turn into a full braille keyboard.

Check out the gallery below for more views of the Siafu concept laptop.
