Imagine walking into a giant digital butterfly garden, releasing virtual butterflies with your smartphone, and watching them appear to land in the palm of your hand.
That is the experience now awaiting visitors at Happitat Bangkok, where The Butterfly Trail has made its Asian debut. Created by UK-based Pixel Artworks, the mixed-reality experience transforms a massive indoor LED display into a digital world where visitors can interact with butterflies through their smartphones.

The Butterfly Trail is an interactive mixed-reality experience originally created by Pixel Artworks. It first launched at Outernet London in September 2023 before travelling to other locations in the UK and Greece. (Pixel Artworks)
The experience takes visitors into the fictional botanical workshop and glasshouse of Professor Pelegrin. Instead of simply watching the digital scenes, visitors can use their own smartphones to interact with the virtual world.
They can launch digital nectar at virtual chrysalises and release colourful butterflies. The butterflies can then appear to land in the user’s hand through smartphone-based augmented reality. The experience does not require a dedicated device or a downloaded app. (Pixel Artworks)
This combination of a large digital environment and smartphone-based AR is what gives The Butterfly Trail its mixed-reality character.
And the experience has already attracted considerable attention. In its first year, more than 1.36 million digital butterflies were released, while the experience recorded around 378,000 game sessions and more than 28 million views on Instagram and TikTok. (Pixel Artworks)

For its Asian debut, Pixel Artworks has adapted The Butterfly Trail to fit its new home at Happitat Bangkok.
The experience is installed along the Grand Stairs, where it uses a 385-square-meter P1.8 indoor LED display. The screen stretches more than 50 meters and has been positioned as a major digital feature within the new destination. Recent reports have described it as one of Southeast Asia’s largest indoor digital displays. (泰国居民网)
The large LED canvas gives The Butterfly Trail a very different physical setting from a conventional digital display. Visitors do not simply stand in front of a screen and watch a video. Instead, the screen forms part of the environment in which the story unfolds.
The experience is also closely connected to Happitat’s focus on nature.
Happitat has its own physical butterfly garden. For the Bangkok version, Pixel Artworks redesigned some of the digital butterflies to reflect native species found there, including the lime swallowtail and plain tiger. This creates a link between the real butterflies in Happitat’s outdoor environment and their digital counterparts on the indoor LED display. (Design Week)
The most interesting part of The Butterfly Trail is perhaps not the size of the LED display, but what happens on it.
A large-format LED display has traditionally been used to show videos, advertisements, artwork or other visual content. In The Butterfly Trail, however, the display becomes part of an interactive experience.
Visitors use their smartphones to interact with the digital content. Their actions can trigger changes in the experience, while AR brings elements of the digital world into their physical surroundings. (Pixel Artworks)
This creates a different relationship between people and LED displays.
Instead of simply watching the screen, visitors become part of what is happening on it.
That idea is also reflected in Happitat’s plans for the Grand Stairs. The Butterfly Trail is the first major immersive experience presented there, with other interactive content, including Forest of Time by BoraBora Studios, also planned for the venue. (泰国居民网)

The arrival of The Butterfly Trail gives Happitat another way to connect its physical environment with digital content.
For visitors, the attraction is a playful journey through a world of digital butterflies. For the LED display industry, it is also an interesting example of how large indoor LED screens can become part of experiences rather than simply serving as visual backgrounds.
With its 385-square-meter P1.8 LED display, Happitat provides a large canvas for this kind of content. The Butterfly Trail shows what can happen when that canvas is combined with storytelling, augmented reality and audience interaction.
And perhaps that is the real appeal of this project: the LED display does not just show the butterfly trail. It becomes the place where the trail comes to life.
