I stumbled onto this when looking at the ruby source code, anyone know how to trigger it?

On Ruby 2.7+, run irb, type 'RubyVM', press tab twice.

Super cool, didn't know you could do that :)

You have to try a few times to get the logo or dancing logo

Thanks! Very cool - here's a gif for the curious: https://media1.giphy.com/media/L0eN2GwpS7GOmv5Kk7/giphy.gif

Run irb and input 'IRB.send(:easter_egg)'. Also, if you have the downloaded source, you can just run the source file directly because of the last line of code.

Just copy the contents in a file and

    gem install reline
    ruby yourfile.rb

It is a nice ascii demo of a ruby turning around
