Ok After-Effects people, here’s a t-shirt that will be instantly recognisable to any animator / motionographer / compositor / editor / post-production colleagues, but completely meaningless to the muggles. Let your keyframe-tweaking flag fly!
Comes in any colour, as long as it’s grey, because of course it’s grey, silk screened from a vector file, not digitally printed, so you can collapse transforms on it and it will scale perfectly.
