Henry Lim's 100,000+ piece Lego Harpsichord has been around for while, but it's gotten a bit of recent love in the blogosphere from the likes of Digg. Rightfully so—it not only is good-looking, but manages to withstand the 325 pounds of pressure needed to make the strings playable.

But as much as we like the harpsichord, we find some of Lim's other creations even more impressive. This 14-foot Stegosaurus, for instance, is not only huge, but is almost completely self-supporting using Lego bricks alone. The fact that Lim can lean on the head—held up without any glue or internal non-Lego scructure—is a testament to his engineering skill. (At last update, Lim had not quite figured out how to make the tail completely free-standing.)

Lim also manages to impress with his Audrey Hepburn mosaic. Mosaic work can be done fairly easily with access to digital imaging tools like Photoshop, but the results remain very attractive.
