Well, there is no standard way to design a carousel, just guidelines, so no, it is not required ;) But it always depends on the context is it important to show the number of items in the carousel or not. If the number of items in the carousel is huge, the user can get frustrated if he/she doesn't know how many items there are left. But also, if the number of items in it is huge, carousel might not be a good solution at all.

It would be interesting to see some usability test results from carousel usage.

Thanks for the addition Alice.

Thanks for the comment. I've found that finding a good name for a pattern that is commonly in use can be really difficult. The names also tend to change by time. But we are redesigning out library, and there might be a feature that allows users to change the name of a pattern to what they want...

My suggestion was "User Interface Design Pattern Library Application" but the others thought it was a bit too long ;)

Well, it is just a name, and we think it doesn't need to explain excatly what the app does.

Thanks, we like it too ;) Flickr integration is implemented using Flickr badge, which is a really simple way to bring content from Flickr to here. It works great, but we are actually working on to replace the badge with our own code, which will give us more freedom in showing the images.

I didn't get the design from anywhere, I designed UI Pattern Factory by myself.

You should view the images in original size to see the details.

Hi Anders and thanks for showing interest. We'll blog more often as we move towards the new version to keep you and others up to date of what we are working on.

It is now fixed. Thanks for letting me know about the problem with the video!

@Lucky: You're absolutely right, and I will change the example to a better one soon.
