This experiment was designed exclusively for a screen resolution of 1280x1024 pixels and optimized for Chrome on Windows 7 and Safari 8.0.8 on Mac OS 10.10. While other resolutions will probably work, different parts of the screen might be completely hidden from you. On a laptop zooming out is definitely called for, but that need not necessarily solve all problems.
In the lab this experiment was running on a customized PHP framework. Wherever subjects interacted with each other or elements were randomized, the necessary dynamic information was replaced with static examples for the purpose of this demonstration.
