TEDxVienna Adventures:
Color with light

It does not take much to expand on everything you know about the power of visuals.

Sometimes, all you need is an iPad and a projector.

Sometimes, all you need is some darkness, some lights and the right tool to go on an adventure.

And this is exactly what TEDxVienna did.

Color with light

Founded in 2006, oMai (Office for Media and Arts International) designed the app Tagtool that makes it possible to paint with light. By using your fingers, you can create your own digital animations and let them come to life on every surface imaginable.

Even on buildings.

But coloring with light is not only an innovation in regards to analogue mapping and urban intervention. Its potential for storytelling, both in an educational, but also in a commercial or artistic context, is remarkable. Tagtool makes breathtaking, instant art accessible to everybody, and we couldn’t wait to present this unique instrument to you!

When you play music, you cannot take the chords back; You can just build on the sound you have already created. This is the principle we applied on Tagtool. Once you have drawn something, you cannot delete it. But you can make the best out of it instead.

Fascinated by the power of Tagtool, TEDxVienna Adventures invited its attendees to experience its visualization power themselves.

Little did we know that the outcome would be the most vivid canvas we have ever seen!




The affordable app can be used by anyone. It is designed to follow human intuition, thus every movement feels natural to the user. Just like playing around with finger paint and then breathing life into it with light.  Because of that, Tagtool can be easily operated by kids and serves educational purposes too.

Dovetailing to the educational aspect of this TEDxVienna Adventure, the event was hosted by Markhof by Colearning, the heart of an innovative educational space in the making. In this one-of-a-kind social biotope, children, adolescents and adults learn from each other and grow thanks to each other. The old printing house, built in 1913, now serves as an open hub for arts and science, and is definitely a place worth visiting.
