If you create gadgets or HUDs, it’s always useful to have an easy way of creating good-looking buttons for them. A quick search on Google for ‘button generators’ will produce a host of online generators — fill in (or select) some options, and a button will be created for you to download.
Unfortunately, (and perhaps unsurprisingly), many of them don’t work very well, or produce HTML+CSS buttons (very useful for websites, but not so useful for Second Life).
