How creative are you?  Take this general survey on mindwerx.com and find out. 

Go to http://mindwerx.sauceopen.com/surveys/index.php?sid=1&Itemid=431  - it will only take a few minutes.  You will need to register on the Mindwerx site so you can be advised on how you did, but it only take a minute or two.  When the survey is complete you will see your score and comments related to it.  

Have fun - the survey is more for fun and general information.  It is not a formal test.
