This mod lets players "doodle" on the walls with logo's selectable from the list given. These decals fade after a while but I might make that longer in the actual release of this. The HUDMutator shows (just under your health) which logo you have selected for spraying on the walls. You can select which logo you want to use with the commands "mutate nextdecal" and "mutate previousdecal". To spray the logo use the command "mutate spraydecal".
