I am looking for an operating system that:

  • Under 100 MB
  • Can be booted from and run on a USB flash drive
  • Minimal or no changes to my computer's files, main OS, etc.
  • Preferably Unix based
  • Portable
    • Can run on a variety of hardware
    • Leaves minimal trace (don't want to clog people's computers)

  • FLTDJ personal information manager
  • FlMusic CD player
  • FlRadio internet radio
  • FlChat IRC client
  • Antipaint paint program
  • Fluff file manager
  • NXterm terminal emulator
  • Flcalc calculator
  • FlView image viewer
  • Fleditor
  • Games: Tuxchess, NXeyes, Checkers, Blocks, Sudoku, Mastermind
  • Mount tool, system statistics
  • Software package download and install utility
  • NTFS support
