I've just released Clipboard Inspector, a handy little tool I wrote that monitors the Windows clipboard and displays its contents in a variety of formats. It'll display clipboard data in Bitmap, CSV, File, HTML, RTF, Text, and Unicode Text formats, and you can save the data to a file if you wish. It'll even export clipboard bitmaps to GIF, JPEG, PNG, and TIFF, so it's pretty handy for saving screenshots taken with ALT+PrintScreen. And of course, it's free. Enjoy.
