Hi Brian - this looks interesting.
However, I quickly get an error:
yaw 90 180 270
caught error in sys_timer_z_
|domain error: chkgl2
| gl_paint''
createTurtle 6 6 0,10 0 0,:0 _10 0 NB. notice:0 1 2 result
|domain error: chkgl2
| gl_paint''

dbr 1
yaw 90 180 270
caught error in sys_timer_z_
|length error: rotation
| orientations=:orientations x}~(x{orientations)qnmul axis rotation-y
It does display a graphics window with some text and a cluster of little
pyramidal shapes.
I tried turning on the debugger but the error does not appear to leave the
function suspended.
Any idea what I may have done wrong? I'm using J 9.02 in the Qt window.
Thanks,
Devon
