Obfuscated X-Mas was INTERCAL's 2006 debut album. It features a selection of christmas songs that are algorithmically obfuscated.
- O Binary Tree (3.8 MB) - O Christmas Tree, scrambled into a binary tree and then traversed in different ways.
- Silent Night (11.6 MB) - Layers of permutations of Silent Night, gradually progressing towards the correct notes.
- Bring a Torch Genetic Isabella (18.2 MB) - A genetic algorithm is used to piece together a randomized version of Bring a Torch Jeanette Isabella.
- O Holy Night (15.1 MB) - Markov chains are used to produce new melodies based on O Holy Night with the actual melody highlighted. As the notes become more frequent, the song becomes more apparent.
- Good King Wenceslas (7.9 MB) - The song is rearranged and then put back together using a quicksort algorithm. Recursive subsections of the song are layered over the melody.
- White X-Mas (2.0 MB) - White noise, filtered and festive.
