The Mystery of 611

Some people look for hidden meanings in lyrics of favorite bands.  Others dig for cryptic messages in books.

For me, it's Uglydoll art and calendars.  I look them over closely, hunting for clues to future Uglydolls, or links to Ugly ancestry.  Occasionally I notice something that tickles my curiosity.  Currently the number 611.

Check out how it pops up here and there in the Uglyverse.  What could it mean, other than 6 one hundreds, one 10, and one 1.

It shows up as a  street address here, a time on a clock there. It's all over!

Is it a date of significance from the past or future?

Or perhaps connected to Planck's constant? It has a 611 in it somewhere doesn't it?  Quantum theory fits right in with Uglydolls, time machines etc.  Maybe?  Mina's birthday? :)

Any ideas?  You know how I love a mystery!
