Upcoming Events:

Infinite Scroll

This September at Big Art Rotterdam & Glue Amsterdam

2026 marks Tjep.’s 25th anniversary, celebrated with Infinite Scroll: a series of kinetic sculptures that take the most reflexive gesture of modern life — the scroll — out of our thumbs and into the room. As the image above hints, a free-standing robots autonomously operating a screen, turning an ironic, unblinking eye on the spirit of our own scrolling age. Six perform together at the Codrico Factory (Rotterdam) and the Waag Futurelab (Amsterdam) this September; the work is released as a limited edition of 25 in brass, stainless or corten steel — one for each year of the studio’s practice.

  • A futuristic building with multiple levels, greenery, and windmill structures, surrounded by cows on a grassy field.

    Dream it.

    Grow it.

  • Inside a colorful beauty store with makeup displays along the walls, large promotional posters of women, and a black ceiling with colorful, floral-shaped ceiling lights.

    Sell it.

  • Crowd of people gathered outdoors at night, some taking photos, as they wait for an event to start near a modern illuminated structure with a spiral design, under a crescent moon.

    Love it.

  • Two men working on a large intricate butterfly-shaped mechanical art installation with gears and clockwork components; one man adjusting a wire while standing on a ladder, the other observing.

    Fix it.

Make it stand out.
