Each visitor to the web lab can create a lab tag, a code that can be used to identify them. Visitors can recall their interactions with the experiments in the exhibit by logging onto the web lab site and entering their tag code.

David Sjunnesson, interaction designer at Tellart, said: "All of our experiments have different learning goals, showing how people can collaborate online through the orchestra or how images travel online.

"At the same time if people just come here and have a great time, then that is good too."

As is the norm for many Google products the exhibit is classed as Beta. Feedback from visitors will be used to tweak interfaces and improve the overall experience of using the web lab. The exhibition runs until June 2013.
