In order to communicate with its surroundings, London-based interaction design agency Unit9 has attached an interactive public screen to its building which allows passers-by to fill it with drawings coming right from their smart phones.
The so-called Wi-Fireworks project provides a free Wi-Fi connection. Once people are connected with the network through their phone, the installation redirects the device to an HTML5 page that enables them to make a drawing with their fingers. Whatever they draw on their screens, appears on the windows of Unit9. Click explode, and watch your doodle explode as a firework. Visit the project website to watch a video of Wi-Fireworks.
