David Aiken provided a handy list of Windows Azure Samples; here’s a quick run down:

-Bid Now Sample is an online auction site designed to demonstrate how you can build highly scalable consumer applications, built using Azure and uses Azure Storage. Auctions are processed using Windows Azure Queues and Worker Roles. Authentication is provided via Live Id.
-Windows Azure Management Tool (MMC) allows you to create and manage both blobs and queues. Easily create and manage containers, blobs, and permissions. Add and remove queues, inspect or add messages or empty queues as well.
-Contoso Cycles shows how the Azure Services Platform can be used to build a supply chain application. .NET Services allows messages to flow between companies across firewalls, NATs and routers.
