LEGO is now offering minifigs with magnets! The two themes that are currently available is Star Wars and Knights Kingdom. The magnets used are as strong as the others and are, I assume, glued in place inside the legs. I only picked up the Star Wars set for obvious reasons and there's a couple of reasons why you should get them as well.
First off, they use the flesh tone color for Anakin. I'm not that big of a fan of the flesh tone decision for a variety of reasons but this is not the place to get into the discussion. The huge plus is that the Anakin in this set is the non-light up version, so you get a normal head element, hair, lightsaber, etc. You also get a green Clone Trooper and a Yoda. Nothing extraodinary about these but it should be noted that none of the minifigs come with the LEGO logo printed on the back, like the keychains did. So other than the magnetic legs, they'll blend right into your existing collection. Unfortunately, the legs are glued to the torso so you're pretty limited to making your own minifig with a magnetic personality. Hyuk hyuk hyuk, I crack myself up sometimes. Anyways, check out my last action shot to get an idea of what they would look like. Yeah, I know, big stretch of the imagination.
I so want some of these because the clone troopers will fit on all Lego sets so I can finally have an army... :-D
