NaDa's version goes countdown. Current version is 0.5 (improvement over the 0.9 for Mac), and according to the site, work is being done on 0.0. However this hasn't been changed for a year.
NaDa is a fake-satirical software that "does nothing, but does it very well." "NaDa does nothing for everybody" NaDa is actually a useless and otherwise harmless empty file, one byte small (a newline), compressed and available for download from the "official site." The site is designed to look like an actual professional programming company site, complete with users' testimonials, legal disclaimers, advertisements, etc. The NaDa page actually belongs to the professional site of a graphic artist, Bernard Bélanger. The testimonials are written by "fans" who decided to mail him. The site has had over a million visitors.
Various download options from the main page (zip, RAR, tar, etc.)
