Initial Design

Created with this script
startshape crystals

rule crystals {
crystal { h 81.87 sat 0.8642 b 1.0000 }
crystal { h 81.87 sat 0.8642 b 1.0000 r 90}
crystal { h 81.87 sat 0.8642 b 1.0000 r 180}
crystal { h 81.87 sat 0.8642 b 1.0000 r 270}
}

rule crystal {
blob {}
crystal {s 0.5 y 0.75}
crystal {s 0.5 x 0.75}
}

rule blob {
SQUARE {}
blob {s 0.9 b - 0.1 r 5}
}

Add an extra layer of recursion

startshape gem

rule gem{
crystals {}
gem { s 0.8 r 10 }
}

rule crystals {
crystal { h 81.87 sat 0.8642 b 1.0000 }
crystal { h 81.87 sat 0.8642 b 1.0000 r 90}
crystal { h 81.87 sat 0.8642 b 1.0000 r 180}
crystal { h 81.87 sat 0.8642 b 1.0000 r 270}
}

rule crystal {
blob {}
crystal {s 0.5 y 0.75}
crystal {s 0.5 x 0.75}
}

rule blob {
SQUARE {}
blob {s 0.9 b - 0.1 r 5}
}

Or with this change create a spiral effect

startshape gems

rule gems{
8 * {r 45} gem {}
}

rule gem{
crystals {}
gem { s 0.8 r 10 x 2.5}
}

rule crystals {
crystal { h 81.87 sat 0.8642 b 1.0000 }
crystal { h 81.87 sat 0.8642 b 1.0000 r 90}
crystal { h 81.87 sat 0.8642 b 1.0000 r 180}
crystal { h 81.87 sat 0.8642 b 1.0000 r 270}
}

rule crystal {
blob {}
crystal {s 0.5 y 0.75}
crystal {s 0.5 x 0.75}
}

rule blob {
SQUARE {}
blob {s 0.9 b - 0.1 r 5}
}

Finally add some colour and change the angle

startshape gems

rule gems{
8 * {r 45} gem {h 81.87 sat 0.8642 b 1.0000}
}

rule gem{
crystals {}
gem { s 0.8 r 25 x 2.5 h +25}
}

rule crystals {
crystal { }
crystal { r 90}
crystal { r 180}
crystal { r 270}
}

rule crystal {
blob {}
crystal {s 0.5 y 0.75}
crystal {s 0.5 x 0.75}
}

rule blob {
SQUARE {}
blob {s 0.9 b - 0.1 r 5}
}

Fractal tree with spikes, originally uploaded by Alastair Montgomery.

Fractal tree created in Context Free using the script below.

More context free art




Here is the script, just change the “r -40” to “r 40” to generate the other image.


startshape spin2

rule spin2 {
spin {}
spin2 { r -40 x 1.5 y 1 s 0.9}
}

rule spin {
spikes {}
}

rule spikes { spike {hue =1 sat =0.8016 b =0.9502} }

rule spike { point { } spike { r 10 s 0.95 hue +1 } }

rule point { CIRCLE{} point { y 0.1 s 0.96 sat -0.005 }}
