Not all machines have to be pretty, some are loud, noisy, and above all, messy. This TARDIS aims to recreate the dirty, greasy and messy aspect of dieselpunk. The interior is housed within an octagonal structure made of bricks, cracked and darkened over time. Large pipes rise from the grounds, pumping fresh oil and/or fuel into the central time column, with oil leaking out onto the floor through holes in the pipes. The console glows a warm yellow as steam and smoke slowly vents up around it from the grates in the floor. A thick cloud of smoke lines the ceiling, covering it from view, as glowstone lamps pierce through the darkness to illuminate the small room sections built into the walls by its owner, hidden away behind more pipes running through the walls.
This design is an original built by me.
