Client · Real estate
Berggruen Holdings, the private property company of Nicolas Berggruen, needed to show its available Berlin commercial space without putting it on the open market. I designed and built nbh.immo: a private, owner-direct portal for their Gewerbeflächen, plus its own admin where NBH manages every building, unit and photo gallery themselves. Filterable by use and district, always live and current.

Own product · Interactive art
A browser world made from the paintings of Mimi Ritzler. You play a drop of pigment walking around inside her work. Fifteen of her real canvases hang in two galleries and wake, one at a time, as you do the thing each one is dreaming of. At the end you paint your own and it hangs beside hers. Nothing here was designed by eye: every colour is a real pixel lifted from one of her canvases, and every shape is built by one renderer that turns any form into her nested contour rings. Vanilla Three.js and hand written GLSL, sound synthesised live, the whole first load about 320 KB. Paintings by Mimi Ritzler, used with permission: instagram.com/mimiritzler
