   Yeah, this is the kind of service that I had in mind when I wrote the
rotation filters in libcucul. TOIlet has direct support for it:

% toilet -f term -F rotate
INPUT: Hello, <libcaca@lists.zoy.org>! Prepare to be reversed!
¡pəsɹəʌəɹ əq oʇ əɹɐdəɹP ¡<ᵷɹo'ʎoz'sʇsᴉȷ@ɐɔɐɔqᴉȷ> ´oȷȷəH :TՈPNI
% tr A-Z a-z | toilet -f term -F rotate
INPUT: Hello, <libcaca@lists.zoy.org>! Prepare to be reversed!
¡pəsɹəʌəɹ əq oʇ əɹɐdəɹd ¡<ᵷɹo'ʎoz'sʇsᴉȷ@ɐɔɐɔqᴉȷ> ´oȷȷəɥ :ʇnduᴉ
