A-Shape is an iPad app. It can allow you to create interesting shapes, with affine transformation.

We do an iteration:

for i = 0 to Total Objects
xs = X
ys = Y
x = xs * R * cos(teta) - ys * S * sin(psi) + E
y = xs * R * sin(teta) - ys * S * cos(psi) + F
Object's size = Total Objects - i
Draw the object at coordinate (x,y)
Rotate the object by Rotation Increment

By selecting the parameters, the object and the colours, you may find the result interesting at the end of the iteration.

Here are a couple of examples

Try different objects, colours and parameters, to get different results.

It's in the App Store, enjoy using it. Feel free to send feedback.
