After getting recommendations from both Yuvi and Aswin, I gave a try to the PersonalDNA test. More than the questions what captured my attention were the cool UI controls. (See that what happens if you are a web programmer. What ever be the website you always tend to look at them from the design perfective rather than as a user)
Here are some of those cool UI controls.
Two dimensional select
Empty the bucket
From the source I came to know that the author has implemented then using flash. With the recent outbreak of AJAX libraries its not far from seeing these controls implemented in pure (X)HTML/CSS.
And btw my personal dna report said that I am a free-wheeling inventor and if you know me then you can psych you/psych me
