What would you do with a million dollar advertising opportunity?

Dear fellow Android Army soliders,

I have recently been appointed by a startup branch of a major telecom company. Google has given us an opportunity in which we can display a tile on the front page of the google play store which will be displayed to our customers.

Now, the million dollar question is: What graphic or visual would you put on this tile, and how would you get people to actually enter "your" shelf in Google Play?

Ofcourse I have several ideas- but thought it could be an interesting discussion.
