ImageMagick: CLI for Image Editing
I always found it fascinating the grade-A executable names which imagemagick was able to claim in the global namespace:<p><pre><code>    imagemagick /usr/bin/animate
    imagemagick /usr/bin/compare
    imagemagick /usr/bin/composite
    imagemagick /usr/bin/conjure
    imagemagick /usr/bin/convert
    imagemagick /usr/bin/display
    imagemagick /usr/bin/identify
    imagemagick /usr/bin/import
    imagemagick /usr/bin/mogrify
    imagemagick /usr/bin/montage
    imagemagick /usr/bin/stream</code></pre>
