The best mashups are simple, unexpected, and greater than the sum of their parts. Like tasteofstreep, the Instagram account that combines photos of Meryl Streep with assorted food items. It's a simple formula (Meryl Streep photo + color-coordinating food item + wacky background), but it manages to create the same sort of joyfully demented aesthetic as Lisa Frank.
The account has only been active for a few months, but there are plenty of zany images to enjoy. I personally think the backgrounds are the lynchpin to the whole series; they make the food and Meryls float in a pastel sea that feels like a surreal elementary school portrait. Check out some of my favorite posts below, and the entire account here.
