Swedish born, London based creative Johanna Lundberg has just unveiled a new online project called This Is Sand.

Thisissand.com is a website for play, which changes pixels on your computer screen into digital sand that can be used as building material for cosmic landscapes, sand paintings, mandalas and so on.

It's a joint project with Jenna Sutela and Flash programmer Timo Koro, and the trio state they wanted to create a playground of colours and sound for people to play with - within the computer screen, with the digital sandbox on their site echoing a physical one.

The user is allowed to do what he or she wishes with the elements in the sandbox. Sometimes the resulting pieces are expressive, sometimes they become more abstract.

And just like a real world sandbox, the sand can be smoothed out and re-sculpted again time after time, plus akin to real sand which gets its colour from its origins, the sand used on This Is Sand covers the RGB palette from natural to digital environments.

Even details related to the sound of the falling sand resemble a real life phenomenon - that of 'singing sand' which is found in about 35 desert locations around the world where the wind triggers a low-pitch sound in the natural sand.

Instead of nature’s frequencies, the digital sand generates white noise, which is a random signal with a flat power density. It is considered analogous to white light which contains all frequencies - like the RGB sand on thisissand.com.

The best bit? You can even save your pieces of sand art in the gallery or print them out.
