I decided to take it upon myself to write a text Mandelbrot Set Generator in
Ruby (seeing as I couldn't find any...)

Anyway, here is the code, it's procedural style, not entirely utilizing Ruby
to its fullest, but hey

p ' '
p "NOTE: Do not run this from a console that has less than 128 columns, 130
to be safe! If you fail to do so, then you will see rubbish inplace of the
mandelbrot set"
p ' '

i = -24.00
until (i>=24)
  k = -64.00
  s = ''
  until (k>=63)
    p = 0
    x = 0
    y = 0
    while ((x*x)+(y*y)<4)
    xt = x*x - y*y + (k-23)/43.5
    yt = 2*x*y + i/22
    x = xt
    y = yt
    p = p + 6
    break unless p<260
  end
  case p
    when 1..10: s << 'A'
    when 10..20: s << 'B'
    when 20..30: s << 'C'
    when 30..40: s << 'D'
    when 40..50: s << 'E'
    when 50..60: s << 'F'
    when 60..70: s << 'G'
    when 70..80: s << 'H'
    when 80..90: s << 'I'
    when 90..100: s << 'J'
    when 100..110: s << 'K'
    when 110..120: s << 'L'
    when 120..130: s << 'M'
    when 130..140: s << 'N'
    when 140..150: s << 'O'
    when 150..160: s << 'P'
    when 160..170: s << 'Q'
    when 170..180: s << 'R'
    when 180..190: s << 'S'
    when 190..200: s << 'T'
    when 200..210: s << 'U'
    when 210..220: s << 'V'
    when 220..230: s << 'W'
    when 230..240: s << 'X'
    when 240..250: s << 'Y'
    when 250..400: s << ' '
  end
  k = k + 1.00
end
p s
i = i + 1.00
end

p ' '
p "NOTE: Do not run this from a console that has less than 128 columns, 130
to be safe! If you fail to do so, then you will see rubbish inplace of the
mandelbrot set"
p ' '

gets()

Finally, any feedback is welcome, and I'm just wondering if there isn't a
more efficient way to do this.

Anyway, cheers and thanks for reading
