Anyone seen this nice toy?

It can do sound playback. If you select Square and Mag/Phase View and set all phases to zero you get the "Hilbert wave". It sounds like a square wave. The volume is much lower however. I guess the waves are normalized before they are sent to the sound output. Of course a Hilbert wave has a much higher peak-to-peak value than a square wave of the same volume.
