Back in the late eighties I seem to remember using a unix utility method named 'banner' - (see http://en.wikipedia.org/wiki/Banner_(Unix) It basically took a string of text and 'rendered' it as a larger text 'banner' using each character as blocks to form the original character. It was usually used at the start of print runs to create a heading for multi-sheet reports.
Does anyone know of a C# library that reproduces this functionality?
