I have been playing with the superformula to generate a table in Csound. 
It was most easy to use ctcsound inside csound to generate this. See 
also: https://bl.ocks.org/mbostock/1021103
Here is a quick tryout:
You can change the parameters (a,b,m, n1,..) to make interesting sounds...

pyinit ;Start python interpreter

pyruni {{

# Get an opaque pointer to the running Csound instance
# and print Python version number
p = _CSOUND_
print("\\n  --> Python version number: {}\\n".format(sys.version_info[0]))
# Create an object called cs from the ctcsound.Csound class
# using the opaque pointer to the Csound instance
cs = ctcsound.Csound(pointer_=p)
}}

print("\\n  --> Sample Rate: {}, Control Rate: {}\\n".format(cs.sr(), 
cs.kr()))
