We all love our vitamin D, but there's so much more than sunshine to be happy about this week.Since Tuesday, our pals at the Pershing Square Foundation have been planting seeds throughout the site - funding art, music, health, and sports projects down to just $98 in honor of Spring. Our ever-reliable (and exceedingly generous) citizen philanthropists then got them blooming in no time. In just three days, over 700 donors completed 681 projects.That's $240,000 worth of paintbrushes, mandolins, hula-hoops, and basketballs. Crayons, djembes, yoga mats, and wiffleballs! Color us impressed, you guys.Now, though this opportunity has ended, there are still many great match offers available, and a boatload of projects needing less than $100 to complete. Have at 'em.Thanks again to the Pershing Square Foundation, and to every citizen philanthropist that helped make this celebration of Spring a supreme success!Might your company or foundation consider sponsoring a Double Your Impact or Almost Home match offer?
