What is this dance that characters in Nichijou do during the episode breaks?


I always seen this kind of clip in every of Nichijou episode (but with
different movement). You can see them doing that on this
[Scene](https://youtu.be/pVbCCHbYGNw?t=2m24s)

Is this just some random movement?

As far as I know, it's just an original dancing choreography designed to look
endearing, cute and fun. Kids on the streets don't usually perform a dance
while playing rock-paper-scissors (or jan-ken-pon).
