Enter the Perpendicular Universe

This is a metapuzzle, meaning that it uses the answers to the previous puzzles. Start by writing the answers using the weird font on the keyboard that's visible on the desk of Yew Labs. Then you need to "enter the perpendicular universe" of ⊥IW.

It's time to "enter the perpendicular universe" and travel from MIT to ⊥IW.

When written in the keyboard font and rotated, each answer becomes a new word, plus a single extra letter.

You don't need the rotated words, only the extra letters. The letters should be laid out like on the monitor in Yew Labs (the one in ⊥IW, not the one in our world).
