This one simply is riveting, Sand, piling high into dunes that seem to crumble as quickly as they formed, swirling in unique, psychedelic patterns that no eye will lock-on again. Is this some sort of desert madness? Just swivel the sturdy metal frame upside down and the enclosed multicolored sands begin their descent through unevenly spaced openings, piling up in patterns as kaleidoscopic as they are unpredictable. It’s a visual journey with no fixed destination; your thoughts may carry you to the Great Pyramids as to Fillmore West in ’67. You may not be getting any work done for the next few minutes. This crystal-clear window to the mind’s eye measures approximately 8” x 5 1/2”. Simply a lot of fun.
