I'm bored

Expert /prog/rammers,

The weekend just began and I've got nothing to do. What should I code, and in which language?

Here's the languages I know:
C,
C++,
Common Lisp,
Perl,
Ruby,
and then some Python, Haskell, Java, and x86 Assembly.

1. Code a new renameable virus similar to the 4chan.js Javascript that bypasses the malicious code detection scheme moot implemented, preferably by encryption or obfuscation.
2. Post it on /b/ embedded in an image.
3. Make instructions to rename the image to the embedded virus dot extension, and then to open said file.
4. ?????
5. Shitstorm.
