For some tech-loving adults, few devices are as memorable as the 1990 Macintosh Classic. Now, Gizmodo reports that a programmer named Jannis Hermanns has upped the machine’s nostalgia factor by using LEGOs to make a partially functioning replica of the classic desktop computer.

On his personal website, Hermanns explains that he became inspired to make the imitation as he and his son were playing with LEGO bricks. The programmer “had the urge to build one of the first computers I remember using,” he recalls.

Hermanns ended up building his LEGO Mac for a friend. It runs on a simple operating system called Docker, which can display images and run basic programs. You can check out some photos of the device below, or learn how to make your own by visiting Hermanns’s website.
