Inspired by Orkut (hey, I remember that… wonder if I can still login…) we have the Cosmic Buddy theme available from BuddyDev. Light blue with an icy wintry feel, get it from here.

A nice looking custom theme for BuddyPress found over at DeviantArt. The original dev made it for a local band, and kindly offered it for download. Swap out the graphics and you have a whole new theme.
Download link is here, as it’s tiny & hard to find on the DA site.

This is a child theme created for Thematic. You can use it with Buddymatic by changing
Template: thematic
…
/* Apply a basic layout */
@import url(’../thematic/library/layouts/2c-r-fixed.css’);
/* Apply basic image styles */
@import url(’../thematic/library/styles/images.css’);
/* Prepare theme for plugins */
@import url(’../thematic/library/styles/plugins.css’);

This is a lightly skinned BuddyPress child theme with a cool light blue color scheme. It’s just enough of a difference from the default to be pleasing.
