I remember rather haphazardly working these out while seating awkwardly on
Tony Guntharp's livingroom couch in the early days of
Damage Studios (think before it had any employees, when Tony was the only founder, and it wasn't even named Damage Studios). The flamethrowing one is particularly stupid, but at the time I was throwing ideas out in a freeform space.
The left hand on the first char always reminds me of what I kept trying to steal from the work of Howard Chaykin circa his
Blackhawk series.
