Well, now that borodino23 has started us off with the idea of subdividing each state into Canadian-style ridings with a target population size of as close to 110,000 as possible, I figured I'd take a crack at my home state. With a population of over 3.8 million, Oregon would get a whopping 35 ridings. That's just one short of the number of districts Texas will have in the 113th Congress! Okay, so Oregon isn't the biggest state in the country, but we're a proud lot up in the Beaver State.
Right then. I'm going to label each riding according to the color given in Dave's app; some of these appellations are more descriptive/accurate than others, but fortunately, I've already given each riding at least one possible name, which helps if you're familiar with Oregon geography (or if you look at the area views!). I do my best...

So, from this map, I gather we have about a 23-7-5 split, which actually tracks pretty closely with the current 4-1 split (on what is a 3-1-1 map, at least on paper).
The riding with the lowest white population (61.2%) is unsurprisingly Salem North, which is reasonably likely to elect a Latino out of a Democratic primary, though the lowest white VAP (67%) belongs to Powell–Government Island in Multnomah County. The riding with the lowest minority percentage is the dazzlingly white South Umpqua–Siskiyou–Grants Pass West (89.3% white population, 91.2% white VAP), though it has some close competition from Veneta–Roseburg (89.1% white population, 91% white VAP) and Bend–Deschutes (88.8% white population, 91% white VAP), among other ridings.
Current representatives are in:
West Portland–Raleigh Hills (Rep. David Wu, Democrat)
The Dalles–Mount Hood–Hermiston (Rep. Greg Walden, Republican)
Portland Int'l Airport–Maywood Park (Rep. Earl Blumenauer, Democrat)
Springfield–Cascades Wilderness (Rep. Peter DeFazio, Democrat)
Oregon City–Sandy–Newberg (Rep. Kurt Schrader, Democrat)
