• Alex Engelberg, a tech worker from Seattle, made a Slack costume for Halloween and totally nailed it - even down to the snappy notification sound. 
• Watch the video below with the sound on and enjoy.

Alex Engelberg, a tech worker from Seattle, tweeted a video of his Slack costume, and it's so creative, we had to share. Take a look for yourself and enjoy (just make sure you have the sound on): 

People on Twitter seem to be enjoying the costume. Here are some of our favorite reactions so far:

Shortly after Engelberg posted his video, the people at Slack saw the costume and tweeted at him to show their appreciation:
