The Mekaniskt is a robotic Tetris, an arm that can suck pieces, moving and rotating them to make the perfectly fit in place using Nintendo NES-like controls. The only problem: the lines don't disappear.
This problem begs for some kind of ACME disintegration ray to be installed at the bottom (or like some readers say, a conveyor belt. We like deadly rays better, though.) In any case, it comes straight from Sweden, the Nordic lands of Europe where Earth is ruled by blue-eyed Valkyries and vodka and salmon is the breakfast of the champions, so even if it wasn't cool—which it is—that's enough reason to talk about it.
