This is my favorite part of the whole scope.
Here is not my personal belief but an old observation that I have proved through a few experiments: “If you give your swag concept & design more attention than companies usually do, going beyond a logo on t-shirt approach, it becomes a killer marketing instrument for growing brand awareness”.
And it is an even more powerful tool in dev communities. There is no better way to spark a stranger’s interest in what a company does than with a t-shirt with a cool big print — besides a nicely maintained GitHub, of course!
Going back to Jolocom t-shirts and hoodies: both prints consist of a HackingForSSI hashtag, a Jolocom logo, and a git hash — the number of the latest commit in the Jolocom repository on the day t-shirts were sent to be produced.
