RudraRUDRAknows depth. — portfolio

Instead of a list of links, a place to wander. Walk down a stepwell modelled on Chand Baori, one storey for each project, and step through a doorway into a room that tells that project’s story: what it does, how it looks and how it sounds. The deeper you go, the longer the echo.

• 01Walk it on a laptop or a phone, nothing to install
• 02Each room tells one project’s story on its walls
• 03Dawn, day, dusk, night or monsoon rain, each with its own sound

Garba is danced in rings round a lamp through the nine nights of Navratri, but its music is scattered across cassettes, nonstop sets and badly labelled uploads. PlayGarba gathers 1,832 songs in one free place and plays each one inside a garba night: the band on stage, the circle clapping in time, and you and your partner in the ring.

• 01Sixteen venues, from an open ground to a lane between houses
• 02Stand in the circle, up by the band or far off on the chairs
• 03Friends on their own phones hear the same song at the same moment

A farming company in the making, growing food indoors with machines moving the crop. The whole farm is designed as one system, plants, robots and software together, and walked through in 3D long before anything is built.

• 01Plants, robots and software designed together
• 02Walked through in 3D before anything is built
• 03No numbers shared until they’ve been measured

Drawing software for independent architects, where a wall is a wall and not just two lines. Draw the way you already do in CAD, and the plan quietly becomes a building, with rooms, doors and levels that every drawing shares. In the browser, or as an app on Mac, Windows and Linux.

• 01Your CAD shortcuts work from the first day
• 02Change a wall once and every drawing follows
• 03Opens the DWG and DXF files you already have

Book a physiotherapist in India for a clinic visit or a session at home. It works the way care works here: prices in rupees, your +91 number, and every therapist checked against their council registration. The physio keeps the whole fee.

• 01Every physio checked against their council registration
• 02No commission: the therapist keeps the whole fee
• 03Over a hundred plain-language guides to conditions and recovery

Sculptural lights for double-height rooms in homes, hotels and lobbies. The first, VORTEX, is 240 leaves of light falling 4.8 metres from the ceiling, turning slowly, about a third of a turn a minute. What a client sees in the render is exactly what gets engineered.

• 01VORTEX: 240 leaves of light, 4.8 m tall
• 02It turns, slowly enough to feel still
• 03The render and the engineering never drift apart

An iPhone and iPad app for learning Sanskrit, in English or in Hindi. A few minutes a day along a palm-leaf path: hear a word, say it, write it, and find out why it works the way it does.

• 01A few minutes a day, in English or Hindi
• 02Pronunciation counts: a long vowel is never let slide
• 03Every line of Sanskrit checked by a qualified reviewer
