Which theme Elgg website is using?

Hi,

I am new to Elgg and chosen it for my new website. I am coming from WordPress and would like to learn and contribute on Elgg.

I have tested almost all theme plugins in repository but unable to find one which matches Elgg.org theme.

I believe this one is customized version of Aalborg theme. It would be great if this theme is also published in repository if that is not possible at least one post on How to customize Aalborg to match this theme.

I really like the Typography and look feel of this website.
