“Reveal” Window by Adam Frank isn’t cheap, but we love the idea: a light source projects the silhouette of a distant tree swaying in the breeze ($450 at risd | works). 2. Artist Mary Temple creates the illusion of sunlight using latex paint in her installation works. We’d love to try a DIY version of her paintings, but we’re not sure our results would measure up. See more of her projects at marytemple.com or Mixed Greens. 3. The Bright Blind by Makoto Hirahara is a simple idea: a light source behind a set of traditional blinds. Even though we find the blinds a bit depressing, we bet someone out there could rig up a swanky DIY alternative. 4. The same Sunprints we made as kids are back big time and a set of leafy prints up on the wall would definitely add some brightness to the dark days ahead. 5. It's not exactly sunshine, but natural spectrum lighting is supposed to have all kinds of mood and skin-enhancing benefits. We like the slightly vintage industrial look of this Natural Spectrum Illuminated Mirror (129.95 at Verilux).
