We're well into the 21st century, so perhaps it's not surprising that somebody finally decided to render the tried-and-true skateboard a major update. Enter the Post Modern Skateboard—at least, that's how it's being marketed. Thing is, this contraption has no board to speak of.
As CNET points out, the Post Modern Skateboard—basically, a $100 pair of 10-inch, round wheels with foot platforms—seems to be more spiritually akin to a caster board, a two-wheeled, skateboard cousin consisting of two decks joined by a metal beam. But seeing the skater's two feet moving independently in this video reminds me a lot more of roller blading or figure skating than anything else.
The "board," however, does come with an extendable rod that can be used to connect the two skates.
