We’re excited to share that ToyPro has published a wonderful article about our latest creation: GBC 60 Funhouse!

It’s always an honor to see our work featured by one of the largest LEGO® parts retailers. Their article takes a closer look at how the GBC 60 Funhouse transforms the LEGO® Technic Airbus H175 Rescue Helicopter (42145) into a colorful, action-packed Great Ball Contraption full of movement and clever engineering.

A big thank you to the ToyPro team for the fantastic write-up and for supporting the LEGO® builder community!

We absolutely love seeing builders take our designs and make them their own!

GBC builder Tomáš Ullrich incorporated our Geneva Drive mechanism into his own Great Ball Contraption, and the result is fantastic. 🤩

Seeing our building instructions inspire new creations is exactly why we do what we do. It’s always exciting to watch the GBC community innovate and build on each other’s ideas!

Check out the video below. (also check out his many other fantastic GBC videos!)

The folks at Brickworld Chicago 2026 did it again!

Their latest Great Ball Contraption layout is putting the spotlight on our incredible GBC Glow Balls! As the balls travel through a mesmerizing network of lifts, ramps, and moving mechanisms, they create a stunning glowing effect that takes the Great Ball Contraption experience to a whole new level.

From smooth ball flow to eye-catching illumination, this layout is a perfect showcase of how our GBC Glow Balls can transform any GBC into a captivating display. Whether you’re a LEGO Technic enthusiast, a GBC builder, or simply love kinetic creations, this is one you don’t want to miss! Great Ball Contraptions are designed to move balls continuously through interconnected modules, creating fascinating mechanical displays.

Imagine your own GBC glowing at events, exhibitions, or in your LEGO room!

There’s nothing better than seeing our building instructions come to life!

A huge thank you to Paul Beugelsdijk for building our GBC 61 – RAAF module and for sharing his experience with us.

“What a fun build! Attention to detail of the build will result in a very satisfying and reliable GBC.”

Paul even took it a step further by designing and adding his own return ramp, creating an even smoother ball return and adding more action to the module. We love seeing builders put their own creative spin on our designs!

Paul also shared a wonderful story about how his passion for building started. After his family emigrated from the Netherlands to the USA in 1956, one of his favorite Christmas memories was receiving a Tinker Toy set—a building toy that sparked a lifelong love for creating, eventually leading him to LEGO® Technic and GBC.

Watch Paul’s GBC 61 in action here and if you’d like to build your own GBC 61 – RAAF, you can find the instructions here.
Thank you again, Paul, not only for sharing your build and story, but also for leaving us a wonderful review. Happy building!

🎶 LEGO meets vinyl — now LIVE in action.

A few weeks ago we showed you an incredible fully functional LEGO record player built by one of our customers… and you loved it.

Now we’ve got something even better 👀

This new video shows our custom LEGO turntable needle performing LIVE at Oeiras BRInCKa 2026 — and yes, it’s playing real records.

Huge thanks again to Jorge Pereira from Portugal 🇵🇹 for pushing this build to the next level.

Seeing it in motion, in a real event setting, makes it even more impressive. This is what happens when creativity meets precision engineering. 🧱💡

Would you try building one yourself? 👇

Back in 2018, we created the GBC 27 Pinball Madness Machine — an interactive Great Ball Contraption built from the LEGO 42076 Hovercraft set. A full-on pinball experience with moving mechanisms, manual controls, and endless fun.

And we still love seeing it come to life all over the world 🙌

Check out this awesome fan build in action by Rollen and Sage (We Game to Please Workshop, USA) 👇

The energy, the creativity, the gameplay… this is exactly why we build GBCs ❤️

👏 Huge credit to Rollen and Sage for this fantastic build and video!
