In case someone asks , the logo is made with the Orokin Language (referred to as Tennobet by Digital Extremes). It is simply an alphabet that can be used to replace the Latin Roman alphabet with some more fancy in the game. The alphabet was released to the public on October 30, 2014.
To recreate the speedrun.com image, I used TennoTyper by Clarvel (original post). This allowed me to simply export a transparent image of the phrase "speedrun.com" to GIMP for touch ups and coloring. It took about 3 hours to create, modify, and upload.
For more information on the language, there is an article for it on the wiki. There's also the actual alphabet cheat sheet available there too.
