Not mine (I wish), but a motorsport company based up North called Bad Obsession Motorsport. They are basically transferring a Celica GT-Four running gear into an old mini 1000.
There are about 10 vids on youtube channel showing the build so far and it has a great level of detail. Some excellent engineering shown, welding, fabrication. It just goes to show how complicated conversions can be even when you do it properly.
I'd put the links up but my work PC blocks youtube (!) so if you just search for 'Project Binky Mini 4wd' on youtube then I'm sure you will find it. I will post the links tonight.
Some of the vids has some swearing, nothing too rude just be warned
