This mod was written after this conversation on IRC:
<VanessaE> [...] suicide booth that actually crashes clients [...]
[...]
<Calinou> add suicide boots then
[...]
<Calinou> nodebox that represents boots
<Calinou> walk on it == die
So I made a suicide boots mod. It adds a nodebox pair of boots that will kill you when you step in.
Have fun.
