Absolute Johannes factotum
- SCP-1758 (?)
- SCP-1758 is a normal-looking violin from the 1920s that has a strange effect when a man plays it. Anyone who hears the music immediately stops what they are doing and pays full attention to the player. After the music stops, these listeners will loudly praise the player as one of the best violinists ever, regardless of their actual skill, for about 30 minutes. The quality of the music itself is also affected by the player's confidence and happiness, sounding best when played by someone who feels good about themselves.
- Chamber of Art and Curiosities, Ambras Castle (?)
- The Chamber of Art and Curiosities, or "Kunst- und Wunderkammer," at Ambras Castle in Innsbruck, Austria, is a 16th-century cabinet of curiosities created by Archduke Ferdinand II. This collection is notable for being the only one preserved in its original location and is considered one of the oldest museums in the world, systematically organized within a purpose-built structure. It features a diverse array of items, including armor, weapons, natural oddities, scientific instruments, musical instruments, and a unique collection of portraits, some depicting individuals with unusual conditions like extreme hirsutism (Ambras syndrome) or notable historical figures such as Vlad the Impaler.
