I’ve pointed out geodrawing before, in which one uses a GPS receiver to record a track of some artistic merit. There’s a new one up that’s quite an achievement: Traverse Me

The University of Warwick campus map was drawn on foot at 1:1 scale with 238 miles of GPS tracks walked over17 days

I responded to the structure of each location and avoided walking along roads and paths when possible.
The route was recorded with GPS technology and was walked in stages over the 300 hectare site.
My shoes turned brown in the dry fields and they turned green in the long grass.
Security was called on me twice on separate occasions and I lost count of how many times I happened to trigger an automatic sliding door.
