This is just a short video of me shooting a portal at a wall and waving at myself from playing around with some things in after effects. It's quite rough and no where near perfect, but as someone who is learning lots of new AE tricks, I'm quite proud of how quickly I managed to do this, make it look not bad and the fact that I worked out how to do most of it myself.
Side note: I also don't own a portal gun, portal gun replica or even a toy gun any more and so I had to resort to using my watch instead, as silly as that is.
This is the full video of my very short portal skit.
