The World Trade Center mission postcard on a wooden table: the sun's layered orange arcs at the left edge, the eight planets in a row across a black field, and the walk's QR code at the lower right.

NYC · World Trade Center

5×7 keepsake postcard for the WTC walk. Commissioned artwork.

$30 for free shipping — add The Sun Card and you're there.

What it does

  • It sets the scale. Point your phone at the card and the app knows exactly how big it is — that's what lets it draw a planet at true size on the pavement in front of you.
  • No app to install. Scan the code, and the walk opens in your browser.
  • The back is an AR target too. If you'd rather not carry the wallet card, hold up the postcard instead — it's tracked at its own true size.
