A version of Bubble Universe that runs directly from a bootloader. No other operating system required. Just an x86 computer that supports legacy BIOS booting.

To try it for yourself, download from here...
github.com/movievertigo/Bootloader-BubbleUniverse/releases
...and use your favorite bootable drive maker to write it to a device. (If you're using windows I recommend Rufus for flash/hard drives and RawWrite for floppy drives. Linux and Mac users should use dd)
