If you've abeen living under a rock and have yet to visit the The Leonardo museum on Library Square—now is the perfect time to time to set aside a few hours.

Salt Lake's The Leonardo museum of science, art, technology, creativity and innovation is celebrating through January its namesake with the totally engrossing exhibition "Leonardo Da Vinci: The Genius."

Using hundreds of eye-popping exhibits, including 75 full-sized reproductions of Da Vinci's many inventions—a parachute, a glider, two "air-screw" designs for what we now call helicopters—the exhibit offers a window into the mind of a Renaissance man.

"The Genius" not only explains Da Vinci, but pulls together the complex mission of The Leo museum to spark creativity in humans of all ages. Note: This is not a "kids' museum" exhibit—though The Leo will be providing many hands-on opportunities to connect with the creative mind of Da Vinci. "The Genius" will fascinate art lovers, amateur scientists, "Dr. Who" fans, military history aficianados and geeks of all ages.

The highlight of the exhibit is a mini-exhibit that investigates Da Vinci's most-famous painting. "Secrets of the Mona Lisa" turns a  240-megapixel Multi-spectral Imaging camera on the masterpiece. Dozens of mysteries surround the girl with the odd smile (you may have read recently about a second "Mona Lisa" turning up in a Swiss bank vault.)

"The Genius" exhibit solves at least one of the riddles—why the heck doesn't Mona Lisa have eyebrows or eyelashes? A 16th Century wax job?
