Gaussian blur is a common image convolution operation. Laplacian edge-detection is also a common image convolution operation. Today, I discovered that doing a Gaussian just before the Laplacian (Laplacian of Gaussian) yields a fun neon-sign-looking effect...

» Gaussian » » Laplacian »

Without the Gaussian blur, the Laplacian is a lot more sensitive to noise...

Looks cool, but are their any applications outside ripping off a different logo?  I don't really know what you're talking about, but it looks like you're relying on the lighting used in the Google logo.  How could you create a neon-sign-looking logo with your own design?

Can you give me an example of "your own design"? It'd be interesting to see what this filter'd do to it.
You could make some totally weird stuff...
