I found an awesome new site today, VignetteBricks.  These are some of the entries from a Brick Science contest he helped judge last year. 

Eureka!  (Archimedes)


Louis Pasteur (Pasteurization, vaccination)

I love the look of the lab bench in this one, it has a scientific and historic feel of authenticity.


Mendeleev (The Periodic Table)


Alfred Nobel (Dynamite, Nobel Prize)

This lab bench is awesome too!

You can see more at the post here.  The entire VignetteBricks blog is filled with Lego goodness, so check it out!
