Fun with dc

2006-12-28

Something I wrote a couple of years ago:

ASCII Mandelbrot:

[lolssdsl0lqx]sx[1+lddd*lld*-ls+dsdrll2**lo+dsld*rd*+4<kd15>q]sq[q
]9ksk[d77/3*2-ss47lxx-P1+d78>0]s00[d23/.5-3*so0l0xr10P1+d24>u]dsux

Quine:

[91PP[dx]93PP]dx

(dc is an RPN calculator. It’s one of the oldest Unix utilities.)
