Explore is Flickr's way of showcasing the most interesting photos within a given point in time -- usually over a 24 hour period.
Flickr receives about 6,000 uploads every minute -- That's about 8.6 million photos a day! From this huge group of images, the Flickr Interestingness algorithm chooses only 500 images to showcase for each 24-hour period. That's only one image in every 17,000!
Considering that the overwhelming majority of these images are photos, not paintings, I am honored indeed!
