There's a good chance you've seen the drawings of Leonardo da Vinci, but now a new app lets people fully appreciate what makes them so amazing. The "Leonardo da Vinci: Anatomy" app lets users pour over every single one of his 268 detailed drawings of the human body.

They can zoom in to see just how detailed Leonardo got, and some of the drawings have even been turned into 3-D models, for users to better understand just how well he understood anatomy more than 500 years ago.

If that doesn't help, there are also expert interviews to lay out why they are so impressed with how accurate his sketches are.

Users can also get close on his well-documented "mirror image" notes, view them with a virtual mirror and translate them.

"Leonardo da Vinci: Anatomy," which was created to coincide with an exhibit of his drawings at the Queens Gallery in Buckingham Palace, is an iPad app for $13.99.

From blueprints of the human body to actual blueprints, there is now a game called "Blueprints 3D." Users choose a category from architecture to electronics to space to animals.

What they then see as they begin a level is a bunch of scattered lines, and the goal is to twist and rotate the lines so that they are in the perfect place to recreate a blueprint of something, from the Statue of Liberty to a hamster. Users do not know what it is they are done.

There are three levels that make the app increasingly harder.

"Blueprints 3D" is an iOS app that, for a limited time, is just 99 cents.
