How about drawing all the rectangles with .fillRect()

.setColor()

You can alternate between the colours by taking the first of the
following seq every time you set the color:
(cycle [java.awt.Color.black java.awt.Color.white])

Geia sou Stathi,
If I understood correctly, you propose filling rectangles instead of
drawing lines...that is a good idea but how would I alternate the
colors using 'cycle'? 'cycle' returns a infinitely cycled lazy-seq of
the provided collection. Whenever i call 'first' on it I get the same
value back...they are not alternating! Have I misunderstood? thanks
for bothering btw... :-)

aaa ok sorry...you mean having it as doseq binding...that makes sense! I
apologise for rushing...
Jim
