Ok
How about embossed letters on steves background.....
Something like this.......

obviously this is just work in progress, letters need to be outlined etc colours changed perhaps, all that sort of thing, but don't want to spend hours do something which nobody wants, so this is just a prototype, I will need steve to send me a larger version of the background anyway...
as before comments welcome.............
Ps the H shown as valves is stylised
I did try having the valves pointing towards the C instead of away, but it didn't look right,
i.e the overall column of letters doesn't look correct if brought visually narrower at the base.
