Yes it looks a little like the Campagnolo Record: https://fbcdn-sphotos-f-a.akamaihd.n...88184886_n.jpg
But certainly without the same quality. A campa Record with the big chainring in the inner position: http://farm4.static.flickr.com/3663/...580c280345.jpg (source: http://www.bromptonforum.net/t3165-c...ier-campagnolo )
For the look, if possible, the chainring with a outside position is more aesthetical.
Note that the integration of the chainring on the spider is not a total success for the new crankset of Brompton. And we know nothing about the BB that will be installed on the Brompton bicycle from 2013.

Positive point: for the first time with this Brompton's "innovation", that will be mounted in the factory from 2013, we are no longer forced to throw the right part of the crankset when the chainring is too damaged. Few Brompton bicycle 's owners have (and use) more than one chainring. but I think it will be possible to change the size of the chainring (BCD 130 mm, 5 bolts I guest) without having several cranksets.

I suppose that the Brompton's crank will be always delivered in the (standard) lenght of 170 mm. So there are yet a lot of advantages to think "alternatives". And certainly, when you can keep the same budget for these other "alternatives" parts. And more, it's funny to tune ourselves our "B" sharing our discovers and tricks between friends and fans.
