I surely don't! So to those that voted this FUN piece of Python coding down, you are now about to see what the aim was.</p> <p>However although I have subsequently done what I said I would, that is, to create large digits as an _at_a_glance_ digital readout for a project in Python I have decided not to upload it.

Revision 6. </p> <p>The script it self is very self explaining - the task is simple. *NIX only unless with cygwin perhaps?</p> <p>To start this open a terminal and strike the "Tab" key to get all possibilities (strike y, and strike the space key alot).
