England's 50,000 square miles were denuded of forest in the mid-17th century, primarily to fuel the country's growling infernal engine of industrial development. Now you can reforest England in 13 minutes. SpeedTree plants a million unique trees in 500-square-mile plots in 8 seconds; 100 such plots suffice to undo the work of Charles I's contemporaries.
And these trees are not like the one your fire-phobic auntie retrieves from its box during the holidays. These trees are beautiful, richly rendered root and tree and branch. At the same time, they chew tiny amounts of processor resources. I flew at 130 miles an hour just above the verdant plane I had made, skimming over a million conifers and palms and hardwoods, with nary a hiccup from my 64MB GeForce3 Ti500 512RAM vehicle.
Your first chance to see SpeedTree in operation will probably come at Camelot's Trials of Atlantis expansion. Other users include Warhammer Online and the hotly-anticipated Wish. Judging from these forests, well, I wish I could go there right now.
