Bingo! The ingenious thing you did, was do the Maxis Tower of Babble with 2 players! Which, up until I spoke to you, I was not aware, was possible!?! But it is!!! So, on the the EE...
When you got the achievement, you did not have any turbines under the pylon, but instead put 2 at the lamps... and it worked!!! Well, because of that, Maxis asked you to build the Scalene Device! Well, the two turbines you placed down had beams traveling from them directly to the Pylon (the node!!!) and that is when he said that " two obtuse verticals complete " was because the two beams were going to the pylon. So, my guess is, that if the turbines are placed under the correct 2/3/4 lamps, then the beams would connect properly to the pylon and he would give you the next step!
After talking with Dunsy on Live, he was happy for this information to go public. If it turns out to indeed be the next step in the EE, which it is!!!!!!!!!! please, give a shout out to the man!
There has to be a next step. The last major easter egg was in Black Ops 1 and gave you all perks permanently for the rest of the game. It would only make sense to put in a larger reward then a double points power up uder the pylon.
Also just an idea for the reward after the easter egg, since in Black Ops 1 you get all 8 or 9 perks (can't remember) maybe you get either all perks again, even PHD, Mule Kick, Dead Shot or maybe you get more 'perma-perks' such as perma-jugg and perma-flopper
