Ah the joy of long build times

I'm stuck on level 23. I need a hint. :-(

(Not LOTS of hints though. At least I hope I won't need lots.)

There is a refractor in a square adjacent to the final
bulb that the beam passes through.

(I tried for a minimal hint, feel free to poke me for more.)

Thanks; I will chew on that for a while, and will ask again if I remain stumped. I don't have any graph paper handy, so this'll be computer or nothing...

At least it's blindingly obvious which bulb has to be last. :-)

I just used a computer myself.

Oh good. I was beginning to think I was way too lazy.

OK, I think it's hopeless. I need another hint.

The beam passes through the previously mentioned refractor twice. There's
a single mirror somewhere directly left, and somewhere directly right of that
refractor.

ooo! OK, let's see how well I do with that. Thanks.

HAH!

Phew. Finally. Thanks.

My pleasure!
