I thought that Urho3D could use a logo/icon that uses flat design, so here is my attempt, with a few variants.Here is the link for the .zip containing the .xcf and .psd files.
Made in gimp using paths. The original is 512x512 in size, but the paths can be scaled so it can be made larger if needed (for a loading screen or something).
Also worth mentioning that I had thought about making a new flat logo for Urho before, but wasn't sure exactly what it should look like. Then I recently saw this:Screenshot from Obduction
Thought it wasn't far off from what would make a good logo, and felt compelled to follow through with my idea.
