Showcase of beautiful presentations in Beamer

Question

I would like to know to what extent Beamer can produce professional presentations. The following following are the requirements :

1. The contribution must be a TeX solution to this question.
2. Usage of user-defined packages and fonts is allowed.
3. For drawing the diagrams (Smart Arts or 3D diagrams) `TikZ`, `pstricks` or `asymptote` can be used.
4. The submission should include a short description and a screenshot of the output.
5. There aren't sample layouts. The limit is your own imagination.

Note 1:

1. On 25th May 2014, I have decided to close my question and accept the showcases
2. I have decided to provide a bounty of 200 for the best solution

Note 2:

BTW, I just wanted to know the fantastic features of beamer. So introduced a Showcase question similar to Showcase of beautiful typography done in TeX & friends and Showcase TeX Typography for TUG's Calendar and these are not a part of my assignments ;)
