From the SFMOMA site:
Text 572-51 with the words “send me” followed by a keyword, a color, or even an emoji and you’ll receive a related artwork image and caption via text message.
For example, I texted the words “send me cake” and got a text back (in about 30 seconds) with a pic of Wayne Thiebaud’s “Dessert Tray”.
SFMOMA has about 35,000 pieces in their collection, only a fraction of that on display at any moment. This gives you random access to the entire thing. Fun!
