Reading through Smashing Magazine’s roundups can be a little overwhelming. To help you digest all this info, here are my own personal favorites, taken from their list as well as the sites they linked to

Usability & Interfaces

• A look at advanced search.
• An excellent (and free) pdf book on interfaces and usability with lots of screenshots and real-world examples.
• Designing an account sign up screen.

Design Tools

• A great video of drawing icons using Xara.
• A free tool to automatically generate vector shapes (such as bursts, spatters, etc).
• 4 useful design tools in one bookmarklet (grid, ruler, measurement, crosshair).

Design Techniques

• A cool new technique to incorporate a copyright notice in your images without the user noticing.
• A brand new alternative to FCKEditor or TinyMCE.
• If like me and found sIFR a little confusing at first, you’ll enjoy this tutorial.
