Aleph
About
Aleph among other things, refers to the first letter of the Hebrew alphabet, which later evolved to the Phoenician Aleph and the Greek Alpha. In mathematics and in set theory in particular, the Hebrew aleph glyph is used to denote the aleph numbers, which represent the cardinality (size) of infinite sets. Aleph-0 is the first such number and represents the cardinality of “smallest” infinite set; the set of natural numbers. (In modern set theory there are many “levels” of infinite and infinite sets can be compared to each other through the use of functions from one to another).

Usplash
Usplash is a userspace application that uses the Linux framebuffer interface or direct vesa access to draw a splash screen at boot. In short, it is the program that Ubuntu Linux uses for the fancy boot screen. Below is a compiled usplash theme containing the Aleph logo rendered at 1024×768, 1280×800 and 1280×1024 with 256 colors.
