Iconic American Landscape Photos, Recreated with Junk Food

For their project “Processed Views,” which is currently on view in the exhibit “Changing Circumstances” at the FotoFest 2016 Biennial, the collaborators Barbara Ciurej and Lindsay Lochman have produced cheeky dioramas that pull Carleton Watkins’s iconic images brashly into the industrial modern world. Using all manner of highly processed foods—Flamin’ Hot Cheetos, Coca-Cola, marshmallows, fleshy stacks of bologna—they recreated the photographer’s famous landscapes from Yosemite and other California sites as garish candy lands.

Formation of a polyaromatic imidazole based compound. 

I used quite harsh conditions to prepare this compound (polyphosphoric acid and 180 °C), but instead of obtaining a black mess as usual, I obtained a deep blue reaction mixture with a white mass floating on it’s surface and some white crystals sublimed out from it to the wall of the flask.

twelve Essek Thelyss valentines/pick-up lines that no one asked for

Are you a Gravity Sinkhole? Because I’m feeling a powerful attraction to you.

Can I quantum tunnel my way into your classically forbidden region?

My favorite food is soups, but I’m thinking of eating out tonight.

Do you have truesight? Because you see right through me, valentine.

Let me show you a kindness.

No war crimes tonight, valentine. Unless you are into– look, I said I was sorry–

Valentine, I’m walking on air whenever I’m with you.

The inexorable flow of linear time isn’t the only thing I’m violating tonight.

Do you believe in love at first sight, or shall I invoke Fortune’s Favor and reroll my Charisma check?  

Can you clear the cats off the bed, valentine?

Have you been bound to a Luxon Beacon? Because I think you’re conse-cute.

Of my many regrets, loving you will never be one of them.
