Thanks for your answer.
As far as I understand there are 3 luminator blocks: On, OFF and blinking. Why not just duplicate the ON-Block and replace it with the blinking one? Don't know much about Java but is it that hard to fix this one?
I would use IC2 but as far as I know it is only available for SSP, isn't it?
is there any release date for SMP yet?
[Edit]
Just read that it IS available for SMP. Will check it out. Sadly the luminators doesn't work. Any chance this will be fixed?
IC2 seems quite buggy to me...
