Cholinergic Toxidrome was the first flashcard I created.
My original idea was to have a small illustration on the top of the card and pearls at the bottom. However, as the flashcards became more complex, it became obvious that we would be better suited to utilize both the front and back of the card for our illustrations and text.
The character on this illustration was originally planned to be some nondescript dude. Travis however drew himself into the flashcard set and has ever since been known as “the guy on the toilet”. A role later confirmed on the Hydrogen Sulfide Poisoning flashcard.
