The Qlobe

Yusuke Endoh unveiled "The Qlobe," a self-reproducing Ruby quine that rotates its own ASCII-art output 45 degrees each time it is executed, completing a full 360-degree cycle after eight runs. The program, presented in connection with RubyConf, accepts a command-line integer to set any arbitrary rotation angle, with the default 45-degree step encoded in its initial variable value of v=0000. The quine works by embedding its own source code in a compressed, encoded string that it decompresses and unpacks at runtime, then renders as a circular globe pattern using a mathematical formula to map bits onto the output. It matters as a compact demonstration of Ruby's metaprogramming and string-manipulation capabilities, packaged as a single self-contained script. Watch for how the Ruby community receives the trick at RubyConf and whether similar rotation-based quines inspire further experimentation.
