Currently, yoob can interpret 21 languages: 1L_AOI, 1L_a, 2-ill, 2L, Ale, BackFlip, Befunge-93, Black, brainfuck, Circute, Etcha, Gemooy, LNUSP, noit o' mnain worb, PATH, Qdeql, Sceql, SMETANA, SNUSP, Wunnel, and Ypsilax. This installation shows yoob in action, and lets you play with all these esolangs online, using Java Web Start.
yoob is a framework for implementing esoteric programming languages
in Java. It aims to make it easy for a user to experiment with a large
number of esolangs with a minimal install burden (i.e. in a Java Web
Start application), and to make it easy for designers to rapidly
implement and showcase their esolangs.
