MGIFOS
MGIFOS, or My God It's Full Of Stars, is an esoteric programming language created by User:Marz. While 1L consists of 2 characters (+ and space), MGIFOS consists solely of the character *. Its command set is based on Brainfuck.
Language overview
MGIFOS is displayed by a series of stars (asterisks). The program is defined by the number of asterisks in the code.
| Command (binary) | Description |
|---|---|
| 0001 | Move the pointer to the right |
| 0010 | Move the pointer to the left |
| 0011 | Increment the memory cell under the pointer |
| 0100 | Decrement the memory cell under the pointer |
| 0101 | Output the character signified by the cell at the pointer |
| 0110 | Input a character and store it in the cell at the pointer |
| 0111 | Jump past the matching 1000 if the cell under the pointer is 0
|
| 1000 | Jump back to the matching 0111
|
The commands are concatenated in the order required. For example, to move the pointer to the right and then to the left, the binary would be:
00010010
This in decimal is 18, meaning that the MGIFOS code is 18 stars in a row:

Examples
Cat
The cat program ,[.,] consists of 423272 stars in MGIFOS.
Infinite loop
The program +[] consists of exactly 888 stars. Oh lol.
Hello, world!
The program which prints out the words "Hello World!" consists of (approximately?) 4.5287549098E+168 stars.
It has been noted that there are more stars in the Hello World program than there are particles in the observable universe - but this is just a minor setback.
