Thank you, Transmogrify. Will see if I can generate mockups with anti-aliasing. I'm going to switch over to blue and see what comes up. The logo is completely flexible right now so I can ditch the fonts, but I need to incorporate a better version of the globe into the result.
The image is ugly as it is, but the original is quite good. Those little yellow boxes in the picture are the company's heaters. The boss says the picture stays in some form.
I will check out the sites you recommended.
I really appreciate the time you took to write your post.
