I like that its very good. My only slight suggestion (and it is off topic somewhat) the attribute cycling does not seem to suit it. I'd suggest either just blue/black or perhaps none ? Blue/Black is quite easy to do, the 'C' projects both have this.
Yes, I think just black would be suitably sombre.
EDIT: For what it's worth, I've just re-uploaded the file with the above suggestion implemented (attached to original post on previous page of this thread).
If anyone should be apologising for taking the thread off-topic, it's me, as this doesn't really have anything to do with Norman Sword's original post/attachment (I'm not sure how I ended up diverting it with this particular micro-project!)
