Apple's ad agency TBWA Media Arts Lab has started placing outdoor ads in the U.S. to highlight several suites of more niche, artistic apps and a set of drawing apps, foodie apps and music apps.

One ad shows off an app called The Food Book developed by Oomph Technologies on behalf of Oxford University Press. Geared specifically towards "Australian secondary school students", the app has never hit the top 500 list on the App Store in any country nor has it ever received a single user review.

Then there's another app called Mitypewriter, that promises to replicate the feel of a manual typewriter. The app has a 4-star rating, but it has been reviewed less than a dozen times.

Then there's ArtRage, a painting app that's quite popular in a couple of countries. The current version of the app has just a two-star rating on the App Store.

The campaign seems to be highlighting all the gems inside the App Store to make the iPad user's experience more unique. What do you think? Will you even download any of these apps?
