Either by coincidence or intent, these are the bits I've picked out so far:
- http://bit.ly/kebvmk (goes to http://new.spring.me/#!/davevonfair04/q/189035708797719591 )
- Two boxes of letters/numbers, each is 7x7, for a total of 98 alphanumeric chars
- Each box has 21 unique characters (each box is a different set)
- Potential for ROT-1 and ROT-17 on two different boxes of text (1, 17 = 117, yeah?)
- Blue and Green seem to be important (Cortana & MC!), specifically the hex values #1f293b and #1a353a

Aaaand, that's pretty much it so far. Right now I've got a bunch of garbled text. :) Whoever you are, secret santa, you've done a great job of getting me interested!
