> The computer screen shown in the photo is fake. It didn’t turn out well in the photo, so I comped in a screenshot using [Acorn’s](https://itunes.apple.com/us/app/acorn-4-image-editor-for-humans/id634108295?mt=12&at=11l7ja&ct=tss) [Instant Alpha](http://flyingmeat.com/acorn/docs/eraser%20and%20instant%20alpha.html) tool. I also used Acorn to obscure my name on the diplomas and PE license on the wall. Thanks, Gus!
