1.
the amimated elliptic curve: x^3-x^2+y^2+4/27+sin(t/4)=0 (t=time)
2.
the 'stocks' curve (genus 17, time=2pi): (y-4)*(y-1)*(y+2)*(y+3)*(y+4)*(y+6)+(x^2-1)*(x^2-4)*(x^2-9)*(x^2-16)*sin(time/4)-576=0

Quotations
Everything that can be counted does not necessarily count; everything that counts cannot necessarily be counted - A Einstein
Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it - Samuel Johnson
