Dimensional Monocle
From Jenny Everywhere Wiki
Rosen-035, the Crew of the Copper-Colored Cupids' expert on interdimensional rfits, owned a high-tech Dimensional Monocle which allowed him to detect and analyse Rifts. It had a thingumawhizzleometer set in its square frame. In December 2021, as a delayed result of exposure to a particularly powerful Rift, another component, the rift-wave adder-upper, short-circuited, forcing Rosen to bring the device to Doctor Sigma for repairs.
