  • Inside of the code for the beta version of the game, you can find an achievement "The Dark Side of The Moon" with flavor text "oh god", which requires to have 1000 prisms. It is not added to the final game and Orteil left a commentary after it which says: "this is a joke I promise".
  • This building has a fixed distance between each building on the X axis, similar to antimatter condensers and chancemakers.


  • The news ticker message "Can't you sense the prism watching us?" refers to PRISM, a United States surveillance outed by Edward Snowden.
  • Part of the flavor text for the prism upgrade Gem Polish ("Truly, truly outrageous.") is a reference to the 1980s cartoon series Jem, specifically the opening theme. Some believe that it may also be a reference to the League of Legends champion, Taric, but in fact, this is also a reference to the theme from "Jem."
  • The achievement "My eyes" may be a reference to the MY EYES!!! meme format, given the green colouration of the achievement, the green background of the meme, and the meme itself (which features a character's eyes being burned by bright light).
  • The achievement "Praise the Sun" is a reference to a famous quote from the game Dark Souls.
  • The upgrade "Lux sanctorum" may reference the book of same name and is "holy light" in Latin.
  • The unused achievement "The Dark Side of The Moon" is a reference to the Pink Floyd album of the same name.
