Ask HN: EC2 spot price history site to replace defunct cloudexchange.org?

There used to be great charts of the EC2 spot price history at cloudexchange.org, but the domain has expired and the author hasn't responded to an email I sent asking about the site.

Are there any replacements? Does anyone want to maybe fork the site? The code is available from https://github.com/tlossen/cloudexchange.org . I think it could also use some updates to add the newer instance types.

The charts provided by this site are a lot nicer and more responsive than the charts built into Amazon's EC2 console.
