baseMEOW is an encoder/decoder that can store binary as a string of characters that spell out "meow" in some way, similar to base64.
# requires Python 3.7+
pip install baseMEOW$ echo 'hello' | baseMEOW
MeEeeOoWmEeooWwmmEeowwwWw
$ echo 'im a kitty' | baseMEOW
MeEeOwWMeeEEEoOOwwWWWmMmeOoOwMEooWMeeOWwMMMmM
$ dd if=/dev/urandom bs=1 count=30 | baseMEOW
30+0 records in

| test case | base64 runtime (ms) | baseMEOW runtime (ms) | base64 size (bytes) | baseMEOW size (bytes) |
|---|---|---|---|---|
| 10 characters | 11.06 | 202.69 | 17 | 42 |
| 1000 characters | 12.05 | 168.23 | 1337 | 4002 |

| 1000000 characters | 34.74 | 2500.45 | 1333337 | 4000002 |
Using the assembly encoder the runtimes are much better.
