iBlank is an application that allows you to easily create blank/transparent icons. This is ideal for custom modding. I know Doug uses a blank icon under Stack on his dock. It is also nice for lining up your icons exactly how you would like them or use with certain themes. Here is how the app works.
When you open iBlank, you will get the main screen which contains instructions on how to use the application. All you need to do, if you would like to create a blank icon, is select the Create Blank Icon button at the bottom of the page. You will then get a pop-up saying that the icon has been successfully created. Select OK and then hit your Home Button. Your iPhone will respring and you will have a blank icon on your SpringBoard. If you are having trouble finding your blank icon, just make your icons wiggle (tap and hold any icon until they all start wiggling). You can then find it because you will see a space with an x in the top left corner but no icon.
The only issue I have ever had with blank icons is the inability to delete them (see THIS post). So, I was slightly concerned that I would have the same issue with the blank icons created with iBlank. However, I was able to delete the blank icons very easily by selecting the x while the icons are wiggling.
Note: The blank icons that are created are basically blank webclip icons. So, if you are curious, you can find the icons in the var/mobile/Library/WebClips folder on your iPhone or iPod Touch.
