Escher is an artist who, for a 3D enthusiast, is an undeniable wellspring of inspiration. Through his works, he delved into the intricate realm of perspective, showcasing how things can be and appear simultaneously. I've always been captivated by his insights, prompting me to recreate a petite pen holder inspired by his renowned work 'Relativity' with stairs and doors.

Escher's artistic legacy, predominantly realized in black and white, serves as the muse for this monochromatic marvel. Paying homage to his iconic works, this grey pen holder is a tribute to the intricate world of perspectives. Just like Escher's creations, it invites you to traverse its staircases and doors, embracing the elegance of simplicity in a single color palette. In this model, you can ideally traverse it by ascending the outer staircase and, as you continue exploring, find yourself having meandered through the entire pen holder, eventually circling back by turning and flipping it in all directions.
