walk with a signalling light attached to the top of his helmet

That was me in 2001 during basic training (one of the last conscripts in Germany). When we marched to the firing range I had to wear a blinky light right on my helmet. It was embarrassing, but so is the whole service if you are not really into that stuff.

Almost 4k hours in ARK: Survival Evolved. I was one of the 10 players playing it on Linux, with a total conversion mod that was abandoned shortly after the dev was hired by Wildcard. I hated that game…but it was so addictive.
