When Lego introduced the Mindstorms EV3 earlier this year, it bundled building instructions for five "hero" models, several of which can be seen in our CES hands-on. But that complex kit of sensors, modules and bricks lends itself to endless possibilities, and Lego community members have come up with 12 more designs, three of which were unveiled today. These include a dinosaur, a guitar and a whack-a-mole-style arcade game.

From our brief hands-on, all three models seem worthy additions to the original lineup. We enjoyed the sauntering steps of the mini triceratops and the way it snaps and backs off from obstacles, the fun bloops and bleeps of the guitar, and delighted in the sheer satisfaction of bopping a popped "mole." The latter two, particularly, are decidedly whimsical implementations compared to the usual ambling robot -- and we can't wait for Lego reveal the rest of the bonus models later this year.
