Activation · Siam Paragon · Bangkok · 2025–2026
Three original mascot sculptures designed by Ken Kelleher for Nextopia — the sustainability activation at Siam Paragon's 5th Floor, Bangkok. From waste to wonder.
The Commission
Nextopia is Siam Piwat's flagship sustainability experience — a large-scale activation on the 5th floor of Siam Paragon, Bangkok, built around the idea of turning waste into wonder. Ken Kelleher was commissioned to design and produce three entirely original characters: Nexsi, Tobi, and Pye. Each mascot embodies a different dimension of sustainable living — upcycling, food rescue, and circular fashion — brought to life as full-scale sculptural characters placed throughout the space to welcome visitors and anchor the experience.

Character Design · From Waste to Wonder
Each of the three Nextopia mascots was designed to carry a specific message about sustainability — but without the weight of a lecture. The brief was to make environmental themes feel joyful, strange, and impossible to ignore.
The characters draw from the Anchorball universe of Luminal Pop — beings that accumulate, overflow, and transform. Applied to the Nextopia theme, this becomes a visual language perfectly suited to the idea that waste can be reimagined into something with energy, colour, and life.
Nexsi, Tobi, and Pye aren't symbols. They're personalities — each with their own attitude, material identity, and place in the world of Nextopia.




Anchorball · Character Universe
The Nextopia characters are an extension of the Anchorball Luminal Pop universe applied to a specific real-world brief. Each character needed to work as a physical sculpture at scale, hold an identity visitors could immediately read, and carry a thematic message without ever feeling didactic.
The design process started with the material identity of each waste stream — plastic, food, fashion — and translated those textures, colours, and forms into character. Nexsi accumulates the wild colour and material energy of plastic. Tobi is built from organic shapes, fruit, foliage, and perishable abundance. Pye layers fashion waste — fabric, trim, fringe, and flower — into a creature that is herself a walking second life.
The sculptures were placed throughout Siam Paragon's 5th floor, creating waypoints through the experience and ensuring the characters became inseparable from the space itself.
Character 02 · The Food Rescuer
Tobi occupies the atrium's central pillar — a large-scale green sculpture that peers over the railing at visitors below. Grinning, generous, and covered in food forms, Tobi embodies the idea that food waste can be turned into nourishment, creativity, and joy.
The character is rendered in cast material with a glossy, organic surface — rounded, soft, and full of the same playful energy as the Anchorball Luminal Pop characters. Tobi feels like something that grew out of the ground and decided to hang around.
