For a Real Cloud Fix . . .

CALIPSO AND CLOUDSAT. Cloud science enthusiasts are following the progress of two satellites launched earlier this year by NASA to study cloud formation and the relation of clouds to global warming. For more information about the project, visit the Web sites for the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation a.k.a. CALIPSO ( http://www-calipso.larc.nasa.gov/ ) and CloudSat ( http://cloudsat.atmos.colostate.edu/ ), both of which monitor variations in cloud abundance or distribution as well as cloud makeup.

CLOUD. Students at the University of Southern California created a video game that "lets you fly through the clouds, make shapes in the sky and create storms to purify the air." The game, available free at http://intihuatani.usc.edu/cloud was included among the "Top Ten Games You've Never Heard Of" by Game Informer magazine.

CLOUD HARP. Ever wonder what kind of music a cloud would make? Of course you have. And so did the creators of this trippy electronic music installation that used a laser, telescope and computer to read the sky and then produce music based on the density and movement of clouds directly above. You can listen to a sample of the harp at http://www.cloudharp.org/ .

COLORCALM SKIES. If watching C-SPAN isn't relaxing enough for you, you may want to purchase this DVD of magnificent cloudscapes set to soothing ambient or classical music. The three-hour video is in use at children's hospitals in Los Angeles and Philadelphia as well as in W hotels. Available at Amazon.com for $17.99.
