How to build a digital waterfall LED wall display screen for a lobby


Transforming a sterile area of plain and beige taste-less wall, with a 46sqm LED screen was installed to liven up and bring an uber-dynamic sensory experience to a quite ordinary commercial office lobby. Options for visually magnetic motion content are endless within such a vast and custom LED shape canvas, Our customer partnered with a design company to Digitally create an innovative optical animation.

The Water Wall is an hyper-realistic cascade of water – essentially and literally a fluid visual simulation. The concept is in direct harmony with the huge screen’s shape, with the added visual riddle of splash ebbs and flows around edges.

A synchronous sound design further captures the energy of a bustling and, at times, bursting active lobby space.


(1) Fluid Dynamics Challenge: True-to-life fluid dynamics using only computer-generated graphics was a major challenge.

(2) Motion Challenge: Because of the powerful intensity and the rapid, dense visual texture of rushing water, it was important to create a realistic eye-catching experience but not one so ferocious that it would create vertigo or motion-adverse feelings in viewers.

(3) Rendering Challenge: The massive template (3K resolution) for the Water Wall created a huge challenge for rendering the final video.


(1) Real-time physics engines were created to perfect the natural movement of water. This produced such realistic-looking water that it even fooled many people on social media, who believed it was a waste of water. In fact, no water was used in the creation of the piece.

(2) The actual speed of the Water Wall had to be slowed down to be both soothing and believable.

(3) For the massive render, a render farm was used, running more than 70 servers for three weeks to complete the project.


The Water Wall creates a sensation of pure energy as the visual and aural rush of water generates a feeling of fresh anticipation and carefree exuberance. Every day, people walk through the doors of the lobby only to snap a photo on their smartphones. It’s definitely something the passersby and visitors haven’t seen before.

Our LED wall display screen is very similar and was inspired by to Salesforce video wall display in San Francisco lobby’s building.
