Number to LCD

https://gist.github.com/arikfr/11362378#file-gistfile1-txt Goal: write a program that displays LCD style numbers.

Part 1

Write a program that given a number (with arbitrary number of digits), converts it into LCD style numbers using the following format:

   _  _     _  _  _  _  _  
 | _| _||_||_ |_   ||_||_|  
 ||_  _|  | _||_|  ||_| _|  

(each digit is 3 lines high)

Note: Please do NOT read the second part before completing the first. Part of the purpose of this kata is to make you practice refactoring and adapting to changing requirements.

Part 2

Change your program to support variable width or height of the digits. For example for width = 3 and height = 2 the digit 2 will be:

 ___
    |
    |
 ___
|
|
 ___

I saw a screen cast that Corey Haines did on this at

The code for his solution is at http://github.com/coreyhaines/kata-number-to-led

The basic idea is the inverse of KataBankOCR
