Well, not too long ago I created a texture update for a brilliant Elder Scrolls IV: Oblivion mod by VipCxj on the Elder Scrolls files site TESNexus.
His mod adds a Radar system to Oblivion so that the player won't get ambushed by enemies. The textures he used more resemble a modern radar system, and didn't fit with the medieval-fantasy style of Oblivion.
I took it upon myself to recreate the look of the interface to fit the game better. I believe it came out pretty good, but I'll let everyone else be the judge of that.
Here's a link to my mod.
Eventually I would like to see if both mods could be uploaded to ModDB to get more exposure.
