Detour is a popular theme for E17
http://exchange.enlightenment.org/theme/show/2673

There're two gtk+ ports but I think even QtCurve cannot mimic it.

It's no exact clone, but a Bespin interpretation, showing off the new inlay buttons ;-)

You need Bespin >= r1448 to do this,

then import the config:
"bespin import detour.bespin"

and load it
"bespin load Detour"

Or just use the config dialog GUI for this.
