Interesting request. 'Futuristic' and 'digital' seem to be other names for 'techno', which is not my favorite style, so when you said 'not too' in front of those I was intrigued. I would recommend looking in two places: Psy/Ops, which has Reform, Reykjavik One & Two, Transfer Sans & Default Gothic. The other is Device Fonts (Rian Hughes), with September, Gravel, Quagmire, Range & Register.

Of course there are many other foundries with techno styles, but these two foundries come to mind as having some of the less stereotypical 'futuristic' looks, in my opinion. T-26, which also carries Device fonts, has one of the most varied Techno collections.

Maybe Eric Olson would license the typeface he produced for Design Camp. Part of the brief was a font with "traces of FF Isonorm

Or Downtempo, available from Veer (and first seen in the T'phile Critique forums, I believe).

Thanks for the great suggestions! Unfortunately, it looks like the clients are grooving on Crillee... Space: the Final Frontier. Yuck!

Brilliant selection Mike, since "futuristic digital" is
not your favourite style. Some kewl faces too Marc!
