The media highlighted a striking engineering project led by a creator who managed to project a version of DOOM onto a Christmas tree with a holographic look. The result is visually impressive and draws attention for its playful fusion of gaming and holiday decor.
Technically, the decoration is built from a rotating block and a framework of rods supporting RGB LEDs. A 0.5 horsepower motor drives the motion at a high frequency, while a Raspberry Pi 4 single-board computer handles the control logic. All of this is mounted on a dedicated suspension system. To ensure safety, the entire assembly is concealed behind protective glass so that any runaway LED segments cannot cause injuries.
The effect is original and entertaining, though the image quality remains modest. It does not create a true hologram, but rather a convincing simulation that evokes the holographic illusion. The result is clearly more a clever display than a true three dimensional projection.
Earlier reports described another hobbyist experimenting with a shooter displayed on a Christmas ornament. In that case, the interaction was interactive and playable, offering a tangible sense of engagement. Meanwhile, a separate rumor circulated about another redesign inspired by a popular animated franchise. The wider maker community continues to explore creative takes on holiday lighting and retro video game aesthetics.
