A useful prototype keyboard has surfaced and it’s built using two Apple Magic Trackpads. The multi-touch devices can be used as a keyboard as it’s capable of picking up several touches at the same time. The prototype pictured above shows the locations of the keys using printable transparency sheets and to further ensure where the home row is, a dab of clear fingernail polish has been added to guide you. Once the project is done, the creator of this keyboard might laser etch the keys, which should give a little texture to the keyboard itself, helping do away with the nail polish. The source code for this Linux keyboard hasn’t been posted online just yet as there are still bugs, but if you keep hoping, maybe it will be completed and released soon.
