Here's my entry. Prehistoric Communications. It's a fossilised mobile handset from all the way back in 1998. Before Social Media, when dinosaurs made phonecalls and character limited SMS messages, before emoji.
I did use the two point Plaque_Small_LOD0 in front of the exhibit, however i couldn't find the texture so that was made from a screenshot.
Starting off with a flat image of the 5110, I've used the Cut, Extrude, Bevel, Boolean functionality in blender to make a fair approximation of the handset.
