Silicon Graphics released the O2 in 1996 as a successor to its Indy line of Unix workstations, aimed at 3D rendering, scientific computing and technical work for government, defense and energy clients. The company was also widely known for film CGI and pre rendered game artwork from the SNES and N64 era. Pairing that serious professional legacy with the Windows XP startup sound from the early 2000s creates a deliberate culture clash that retro computing communities enjoy sharing as a short, recognisable meme edit.
