1st Video Clue: At the beginning of the video, this puzzle's key is shown and Loki says "Is the axis around which this age of the world will spin" - Indicating that we need to rotate the image at some point.

Imagine looking straight down on a city with tall buildings. Create a colored 3D chart. Each of the numbers represent height in units. Once the chart is created, rotate it 90 degrees (so the tops of the buildings are moving away from you). You should see an image similar to the following: [note that this only works when you have filled in the blank squares with numbers, which presumably came from the fireworks clue - e.g the yellow squares in the third to sixth columns need 7s in them]
