In April, a team from Glasgow School of Art will shoot lasers at the heads of George Washington, Abraham Lincoln, Teddy Roosevelt, and Thomas Jefferson. And they will do it all in the name of preservation.

The Scottish artists have perfected a system of laser scanning giant monuments, ensuring the digital preservation of even their finest nooks and crannies. They have already completely digitized Scottish landmarks like Rosslyn Church and Stirling Castle. The team is also working in conjunction with CyArk, a non-profit dedicated to laser scanning 500 UNESCO world heritage sites.
