365psd - a free PSD every day. Nice resource for tips and tricks for various UI elements.

Geckoboard - build your own business status board. The creator is soliciting feedback here and offers the invite code HN if you’d like to try it out.

Hold it any way you like.

The making of the beautiful Kaleidoscope icon.

Mobile Firefox - There are some interesting UI concepts in their overview video, but my preconceived notion is that this is going to be a bloated mess. I’d love to be proven wrong.

I’ve been trying out rdio for the last couple of days. They seem to have a pretty strong catalog and the UI is well done. My only complaint is that their free trial is only 3 days, after which you need to upgrade to either the $5/month (web-only) or $10/month (web + mobile) plan. They are, however, pretty generous with the invites and I’ve got several if anyone would like one.

CampaignMonitor says goodbye to their Flash charts and reimplements them using Highcharts. I love how they tweaked their setup to allow mouseover events to work nicely on touch screens.

“Apple of My Eye” - shot and edited completely with an iPhone 4. We’ve definitely entered a new era. Watch in HD here.

I love this subtle effect on the redesigned Flickr pages. When you click the star to favorite a photo, they are running a Javascript animation that doubles the size of the star image (actually of the entire Flickr sprite sheet), drops the opacity to zero, and applies a slight easing effect [1]. A similar effect could be done with Webkit and Mozilla CSS effects, but I guess they don’t want to give IE the cold shoulder just yet.

Bounce is a nice site design feedback tool from ZURB. It seems to be a lite version of their fuller-featured Notable app. I’d nominate Bounce for having one of the most creative wait-while-we-process-your-request visuals.
