The museum frustrates me so much. When you first pop in there and it's pitch black, the only effect that allows you to see is the Rainbow one. Apparently when you flip the switch for the second time it doesn't make the museum "dark" per se... it makes it glow an eerie blue. http://gyazo.com/e36cf2ccf748286be9c56bafe2c489d6.png <- LIKE THAT
Ooh - just found something. While the lights are off and you have the glasses on, if you go in the room that you are in first with the lights down as I showed, one of the plants will turn to a different kind of plant and you will go to a secret room with sarcophagouses and such. If this isn't new, let me know. Either way it'll be something to add to the article.
