I love this. Partly because it contradicts your common sense and partly because someone actually went ahead and made a physical contradiction!
Matt parker is fantastic, I've got both his books.
This is great, and I love that the cogs are all interlocking. I just waned to mention, though, that the interlocking is definitely not necessary, the only thing that is necessary is getting the last cog in the chain to be reoriented 180 degrees from the first cog in the chain. The interlocking just hides the twist really well. :)
