looking for a testing program showing effects in light ..

Hi,

Can anyone point me a tutor program (downloadable or web-site) with an interface allowing you to set different amounts of light and watch the effects of the changes. I want to visually feel the effects for ambient, diffuse, and specular lights, and best of all, how materials and lights interact. Any help is much appreciated.
