Here is my proposed new logo/icon for Bugzilla, I used sketchup software for windows in designing this logo and rendered the file through the use of vray 3.4. Using sketchup to produce three dimensional images is much easier than any other software existing.

SOME SCREENSHOTS FROM MY WORKSPACE

The functions that I used is just only lines and circles aside from inserting the text of Bugzilla and ofcourse the paint function. You can see down below some random screenshots from my workspace in sketchup, including vray settings to edit the quality of rendered output.
