Small, but funny programs in Python

• obfuscator.py -- obfuscates any given string by inserting random characters in regular intervals, the resulting string can be then reverted to its original form by using Python slices.
• rotation.py -- simple and insecure rotational "cipher", akin to ROT-13.
• rotation_xt.py -- more advanced variation of the previous code, with custom alphabet which includes cyrillic characters, and longer key (0x0-0xFFF), which is implemented by dividing the actual key in two which are then used in parallel. Also not really secure.
