And speaking of keyboards [1], I've come across two unique keyboards recently. The first one is a Lego Commodore-64 keyboard [2] (which is part of a longer video about a Commodore-64 case made entirely out of Lego [3]). The keys on the keyboard do move when hit, but due to a lucky coincidence, the Lego keycaps can be used on a real Commodore-64 keyboard. Cool!
The second keyboard is one you really have to see—a keyless keyboard! [4] No, really! And it also works as a mouse. No, really! It looks a bit silly, but yes, it does work. No, really! Watch the video. It's bizarre. It's not something I would use (or hopefully, never have to use) but it is unique.
