Answers.Text: Thanks! I checked all of your suggested links. I liked Bricksets theme browser best. It is an eye opener. I knew there were more themes than I could bring to mind, but I had no idea there would be so many.

  In much the same way we had with the [question on categorising bricks](https://bricks.stackexchange.com/questions/214/how-are-lego-bricks-categorized), I think this is something better handled by other sites out there:
  
  * [BrickLink's list of Set Categories](http://www.bricklink.com/catalogTree.asp?itemType=S), or from their [main catalogue page](http://www.bricklink.com/catalog.asp) you can see a dropdown with themes listed.
  * [Peeron's Theme Tree starts here](http://www.peeron.com/inv/theme), with the core [LEGO System themes starting here](http://peeron.com/inv/theme/LEGO/SYSTEM).
  * [BrickSet also has a list of themes](http://brickset.com/browse/), as well as the [Theme Browser](http://brickset.com/browse/themes/) which lists the most popular on the page, and the complete set in a dropdown.
