With all materials gathered I started by booting up Portal 1 and taking screenshots of a test chamber sign. Along with that we also bought a wooden back panel with the same dimensions and two wooden boards (10cm x 1.75cm x 2.5m) for the frame.įor the big numbers and stripes we bought some sticky vinyl tape to cut them out, but we knew we couldn’t get the icons right, so we ordered printable sticky foil. The Aperture Laboratories Logo is from and the icons are from. Eventually we found a 0.5m x 1m white plexiglass panel which was perfect. It had to be in a 1:2 ratio, because we didn’t want to cut it. We went to our local hardware stores and started to look for a fitting panel. So we evaluated both and developed a plan which was a mixture of them with some changes made by ourselves. He didn’t outright link to the aforementioned build, but he stated that he got inspired by some other build. We were pretty impressed and started researching. We thought about buying a poster somewhere, but one day my girlfriend found this: My girlfriend and I are huge Portal fans and one day I thought to myself „You know what would really fit to our Portal Gun? A test chamber sign“.
