The M2x2 workstation by Watt IV is a good example with the innovative reinterpretation of a timeless LEGO element changed into a completely working home computer. Created by Dutch designer Paul Staal, the device takes inspiration from the iconic sloped LEGO computer brick presented in 1979 and scales it up into a useful workstation powered by a modern Mac mini.
The do it yourself centers around the familiar wedge-shaped Slope 45 2 × 2 LEGO piece, a part traditionally utilized in LEGO space-themed sets as a representation of computer terminals inside spacecraft cockpits. Staal enlarged this component to roughly ten times its original size, turning it into a functional housing that blends retro toy visual appeals with modern computing power. Inside the large brick sits an Apple Mac mini equipped with Apple’s M4 chip, transforming the playful idea into a capable desktop system.
Designer: Paul Staal
Rather than serving as an easy ornamental shell, the M2x2 incorporates several useful features that boost its functionality as a workstation. An inclined 7-inch IPS touchscreen is embedded in the front face of the structure, echoing the display screen graphic printed on the initial LEGO piece while providing real functionality. The compact screen serves as a secondary interface, frequently utilized for fast system information or dashboards. Staal, for example, uses it mostly to keep an eye on and manage his
smart home through a Home Assistant interface while dealing with a larger external display. The case includes front-facing ports made it possible for through a USB-C hub, in addition to an SD card reader for easy access to external storage and devices. This arrangement makes sure the gadget stays useful for everyday usage in spite of its playful form element. The system likewise maintains portability aspects motivated by early Apple computer systems, consisting of an integrated manage at the back that makes the unit simple to walk around a desk or work space. While the M2x2 works as a self-contained computer, it is usually coupled with a bigger external screen for complete efficiency. In everyday use, the Mac mini manages the heavy computing tasks while the built-in screen functions as a control panel or status screen

Rather of being purely ornamental, these studs are developed to perform helpful functions. Among them runs as a rotary control that can change volume or media playback, while the other hides a cordless charging bay efficient in powering gadgets such as AirPods or an Apple Watch. The studs themselves remain suitable with standard LEGO aspects, permitting users to connect minifigures or bricks for a lively finishing touch.
The M2x2 is mostly built from 3D-printed parts, making it available to enthusiasts who wish to develop their own version. Staal designed the structure in CAD software and developed it as a modular system consisting of numerous parts. Aside from the Mac mini itself, the required products are relatively simple, consisting of PLA filament, a little touchscreen screen, screws, and a USB-C center. Assembly directions and downloadable files are offered, permitting makers to reproduce or customize the design to suit their needs.
