Not sure how many people follow Droid-Life but last week they had a post for an app called Circle Launcher. It a widget that allows you to access apps easier while on your homescreens. You just press the widget and the selected apps because selectable in a circle or a virtical or horizontal line. I know I am not explaining this to well. Check out the OP up at Droid-Life for a better one.
While you are there also look at Swipepad. This one allows you access a menu of select apps by using a swipe pattern on the screen.
Both apps are worth checking out and can be picked up for free. Sorry for no screens. Its not possible while I am at work
