I play Fez on PC. When I get the ability to check the world map, all the nodes are blank, like no pictures. You can still make them gold, they just don't have any pictures. I don't know if this is a bug or not, because I can't find any articles about this.
Why don’t the nodes in Fez have pictures on them

You have to use the tetromino cipher on the chalkboard.
The answer:
or just press: ↑ ← RT A LT → A ↓, and an anticube will appear
There are a couple of different types, each with a different solution. You'll figure them all out eventually, and doing so is part of the joy of the game, so I'll provide hints and the complete fix as spoilers.
The thick pillars with vertical glyphs on them: in the library/observatory area there's a room with one of these pillars and a part of the level that responds to your controller inputs.
The vertical glyphs are a line of tetris symbols on its side. Each symbol corresponds to a controller input: the 4 'T' blocks are cursor directions, the square is a jump, and the 'S' and 'Z' blocks are RT and LT respectively. Usually completing these gives an anti-cube, but sometimes they open a door.
The tall thin pillars with a square at the top: you need to be in new game+ before you can solve these. Once you're in NG+ try a different perspective.
Stand on the pillar and switch to first person mode, you should see a tetris symbols glyph nearby. Completing these gives an anti-cube.
The U shaped/tuning fork pillars: feel your controller - it's vibrating in a pattern.
The left and right sides of the controller vibrate the pattern you should repeat with LT and RT. Completing these gives an anti-cube.
