I do like a colourful blog post, and they don't get any more colourful than Adriano Zumbo Patissier's macarons.
Here are some of his creations that have featured macarons.
Top row (l-r): Merry-go-round (Jun 2007), Cherry Cherry (Nov 2008), Houdini (Jun 2007)
Middle row: Religieuse (Nov 2007), Envious (Oct 2007), Macaron Marie (Dec 2007)
Bottom row: Yuzu no a nothing (Nov 2008), Christmas Log (Dec 2007)
The dates are when I took the photos, and around the time the cakes first came out.
Macaron Marie and Houdini ...*sigh* ... *swoon*...
