Hello World.

Love this piece of art by Valentin Ruhry. There's something interesting about how it at first looks like a digital billboard, but turns out to be a very low tech version when you get closer.
I don't know if it was the artist's intention, but I really like the way it tries to make digital tangible.

Light Painting WiFi

WiFi networks are all around us but we never see them. The only way we know they're actually there is by looking for the little icons on our phones or computers.
This great little project temporarily changes that by visualising the flow of WiFi signal strength in urban spaces. I really like the way it explores and reveals the invisible nature of online networks by turning them into something very analog and visible.

It's done by using a light painting technique and capturing it in long exposure photographs. Practically it means moving a four metre tall measuring rod fitted with 80 light points though urban spaces while photographing.

Colour sensitive billboard by IBM

As a part of their Smarter Planet Agenda campaign, IBM created this billboard that changes colour according to the colour of clothes people in front of it are wearing. The result is a very simple form of interaction where no technical devices such as mobile phones or cameras are needed to be able to take part in the experience.
