To celebrate the launch of Windows 10 worldwide Windows Central released a commemorative t-shirt featuring the famous 'Ninja cat riding a T-Rex'. We quickly sold over 1,000 of them globally and even did a special India-only campaign.

Due to popular demand the campaign is back for just two days. Evidently, when enough pre-orders come in for the shirt, Teespring relaunches the campaign automatically, and that is what happened here. It came as a surprise to us too. Indeed, we have now sold 1,175 of the shirts and until Sunday, you can still get one yourself.

The ninja cat emblem became a secret handshake of Windows Insiders eventually making its way to the official Windows blog. Now, you can join the semi-secret crew with the ninja cat riding a t-rex busting through the Windows 10 logo. Why? Because it's fun, that's why! You can see Mobile Nation's Kevin Michaluk below sporting his tee.

Styles include:

  • American Apparel Crew – Navy, Asphalt, Fuchsia, Royal, or Slate colors
  • Women's Fitted Tee – Black, Navy, Royal, Slate, Fuchsia colors
  • Women's Flowy Tank – Royal, Dark Grey Heather, Midnight, Neo Pink colors
  • Canvas Poly-Cotton Hoodie – Navy only

Pricing starts at $19, and there is shipping available worldwide. On the back of the shirt is the #UpgradeYourWorld slogan that runs with the Windows 10 launch campaign by Microsoft.

#Upgrading our World
