Error 404 Happy Birthday

Retro pixel-style Error 404 birthday design with blue balloons, confetti, and browser window header

About this card

Celebrate a coder or tech lover with this playful retro computer-themed birthday greeting featuring a faux browser window labeled "birthday.exe" and a bold pixel-style "ERROR 404" message. The design jokes that "the old version of you has expired," followed by a cheerful "Happy Birthday" and a fresh-start line about new data in place. Blue balloons, confetti, and clean minimalist graphics create a modern, geeky feel perfect for colleagues, friends, and IT pros.
