You and I have much in common since I remember 'Sporty before Offensive Security launched BackTrack and I've tried using BackTrack and your artwork is literally the only reliable component of BackTrack Linux.
I am in humble gratitude of the DeviantArt community especially your perseverance since I recall your courage on their hosted forums in face of endless onslaught of kiddie, miscreant and the rest of the undeserved vagaries thrown at you by strafers and dorkers all the while I remained inspired encouraged by YOUR UNWILLINGNESS TO ABANDON THE THREAD AND YOUR INSISTENCE ON BEING CREDITED for Sporty while they incorporated into their distinctive logo. Their actions were nothing less than theft.
It angers me they've stolen your work, aside from the brazen theft of it, their work product is quite substandard and BackTrack serves more as stuffed up business card that is more a collection of poorly organized open source marquis security tools with glorious names but lacking organized development or refinement.
Their OS is just an overglorified piece of shit that attracts adolescents trying to hack their neighbors WiFi or miscreant pedo's trying to conceal their kiddie porn.
