Portal has a ton of funny/cool icons they use for the test chamber warning signs before each leave. Here I have classic ones from the first Portal, ones from Portal 2, a few from the achievements for the games, and several that I made up myself inspired directly from the games.
This image I whipped together to display the various Portal themed icons options I have available for my custom order Portal test chamber poster I have for sale.
If you want to check out what the real poster looks like you can see it in my Etsy Shop here[link]

The real poster looks like a test chamber sign, with a big number and everything, not like this. This is just a mock up to let people see what I have for options. Though I am open to doing custom icons at requests for buyers.
Please respect the work I put into my image. I worked hard to recreate the icons and create my own in the style of the Portal Test Chamber signs. Thanks.
The posters are based off of assets from Portal and Portal 2, owned by Valve. This is a fan work, for fans, by a fan, for the love of the Portal games. There weren't posters out there like this, so the creator made their own and it turns out other people wanted one too.
