GF Adjust the k slider and click on the scene. Shape enter k : 6.2; 3.14; 5.5; 6 .......
http://en.wikipedia.org/wiki/Hypocycloid Group hipocycloid curve parametric equations described: x= a(k-1)cost+acos(t(k-1)) y= a(k-1)sint-asin(t(k-1)) Colors chosen at random. Number k specifies the number of blades hipocycloid when it is integer. K can be given as a decimal, then give beautiful designs and shapes. Try number of PI (3.1415926 ...) Negative numbers give effect epicycloid.http://en.wikipedia.org/wiki/Epicycloid k=3 deltoid http://scratch.mit.edu/projects/leszpio/2814274 k=4 astroid http://scratch.mit.edu/projects/leszpio/2805252 curves-hipocycloid http://scratch.mit.edu/projects/leszpio/2676300 music: Jacek Darabasz-The Last Rumba (cover)
