I designed a special "shell" for the sake of an annual meeting of RAAT #05 : The Divine Comedy.
This 5th meeting starts on 29.12.2018 and ends on 30.12.2018 all night in İstanbul / Turkey. RAAT meeting invites limited number of successful people, along with programmers and designers of "scenes", who reached to divine level on retro programming, electronics, sound (SID) and graphic design on its time and now. It stands for "Retrojen Wise Men Meeting".
