       | I'd suggest looking through the videos on akiyuki's channel. It's
       | a gold mine of novel Lego contraptions and isn't limited to GBCs,
       | although it is majorly that.

         | It's truly a gem of a channel ! This clock was particularly
         | mesmerizing : https://youtu.be/GUdlSYC1cCE
         | 
         | The railway system series is also great, you'll see the step by
         | step construction of the system and later on its use in a GBC
         | event.

         | The undisputed king of GBC. His modules are works of art. So
         | many incredibly intricate and innovated mechanisms with lots of
         | precisely coordinated parts, yet driven from a single standard
         | Lego motor. And the videos are well-shot, clear and to the
         | point.

       | Reading that the GBC standard specifies 1 ball per second, it's
       | fun to imagine a module that puts 1,000 balls in slow moving
       | storage, taking 15 minutes to warm up and cool down

         | Great way to get a maximum traversal rate per module added to
         | the spec.

       | It's also interesting looking at its evolution...

       | Searching for GBC yields a bunch of other kits:
