Here's a logo design I recently did for a band called The Jilted Lovers Club. They wanted it to resemble neon lights. I tried it at first with white in the centers of all the letters but it made the letters seem difficult to read.
Here was the runner up design. The letters form a heart with a dagger through it.
HERE is a link to their website, and you can hear two songs they wrote and recorded. The lead singer is very sweet and her dad is an animator, so that makes her extra cool.
