Electromagnetic Spectrum Options

I'm beginning to delve into a new area of exploration. My idea is to learn to sense/control/generate different frequencies in the electromagnetic spectrum, other than the infrared that comes naturally. At this point, I'm brainstorming on methods, techniques and applications, but the possibilities are endless: from generating visible light, to infrared, ultraviolet, all the way up to mutagenic gamma rays. I'm not really sure about an approach yet, but I'm working on it. I would love to hear any thoughts, comments or suggestions anyone has. I'm thinking about a somewhat Bardon-esque approach, but haven't locked myself in to anything yet.

Its only my opinion ,but I think that you will get more interesting results if you focus on the U.V. side of the spectrum.

You may be right, UV is mutagenic, at the very least, I could dish out some wicked sunburn (IMG:style_emoticons/default/biggrin.gif) . As for an approach to the whole problem, I'm still getting my head around it( and my new OS), but I'll post some results when i get things going.
