Hi,
I wasn’t lucky with the Tor logo, its design qualities in general, especially its performance in small sizes and its inconsistent applications (different shades of purple and green, outlines, gradients and glossy effects …). So I made a redesign. I would offer all file types needed. I hope this mailing-list is the right place to present it and discus it. Please, have a look at the PDF-file: http://www.file-upload.net/download-11010886/_logos_overview.pdf.html
The whole developing system here seems decentralised and an implementation might be a bit cumbersome, but if it doesn’t exhaust me too much, I could also offer further design advice, (re-)designing app icons, making mockups for Tor websites, apps etc. and give it a consistent and professional appearance.
Regards Philip
