+# What's this?
+
+This is a quine-like program.
+
+`q.rb` is shaped like the Twitter logo. It generates the X logo. The output is also a valid Ruby program. When you run it, it returns to the logo of Twitter back.
+
+
+
+## `q.rb`

+```ruby
+                                 k=1;eval(       s=

+```
+
+It will generate `q.rb` again.
