For example, in most languages written in any variety of the Latin alphabet the dot on a lower-case i is not a glyph because it does not convey any distinction, and an i in which the dot has been accidentally omitted is still likely to be recognized correctly.
In Turkish, however, it is a glyph, because that language has two distinct versions of the letter i, with and without a dot.
It is a particular graphical representation, in a particular typeface, of an element of written language, which could be a grapheme, or part of a grapheme, or sometimes several graphemes in combination (a composed glyph).
If there is more than one allograph of a unit of writing, and the choice between them depends on context or on the preference of the author, they now have to be treated as separate glyphs, because mechanical arrangements have to be available to differentiate between them and to print whichever of them is required. In computing as well as typography, the term "character" refers to a grapheme or grapheme-like unit of text, as found in natural language writing systems (scripts).
In a typeface each character typically corresponds to a single glyph, but there are exceptions, such as a font used for a language with a large alphabet or complex writing system, where one character may correspond to several glyphs, or several characters to one glyph.
The Glif may be one of the coolest contraptions designed for the i Phone 4 to date, and you can be a part of its production.
He has had more than 130 singles, albums and EPs make the UK Top 20, more than any other artist.
Clearly this product is something people are interested in. But because of its small form factor (and Apple's minimalist design approach) it will never contain a threaded nut for attaching a tripod, standard on almost all photo and video cameras.
Solutions for mounting an i Phone to a tripod exist (DIY or otherwise) but they are typically bulky and cumbersome.
Gerhardt and Provost are leveraging the crowd-sourced power of Kickstarter to fund the manufacturing process needed to get the Glif off the ground. Here's why the Glif exists, straight from the guys who are making it: "The idea for the Glif was first formed when we realized the i Phone 4 is literally the best camera we've ever owned.
With 29 days to go, the duo has managed to already meet their ,000 goal and exceed it by more than 50 percent. Your donation to the project gets these things made, but you also get the product. With the addition of HD video recording and high dynamic range photography, it's clear Apple is positioning the i Phone as a very high-quality portable camera.

The term has been used in English since 1727, borrowed from glyphe (in use by French antiquaries since 1701), from the Greek γλυφή, glyphē, "carving," and the verb γλύφειν, glýphein, "to hollow out, engrave, carve" (cognate with Latin glubere "to peel" and English cleave).
