 Tropy's wearable time-traveling device was conceptualized early on in the character's design evolution and initially appeared as a belt-like contraption that featured a digital read out displaying the year Tropy intended to travel to.At one point in its aesthetic development, Tropy's time machine was covered in clock gears and mechanisms, including a cuckoo clock on the machine's lower-right area; Zembillas assumed that the details could be created as a texture in Adobe Photoshop and placed over the modeled character's polygon structure.Furthermore, the pistons on the back of the machine were connected to each other through joint-like bearings.
