IFLY is probably what it was.
D)Animated abstract shapes
Here's a solution in node.js. Can be easily transcribed to other languages:
var paint_per_sqf = 1/350;
var wall_area = 250.0;
var gallons_paint = wall_area * paint_per_sqf;
console.log(wall_area.toFixed(1) + " square feet wall will need:");
console.log(gallons_paint.toFixed(12) + " gallons of paint");
c) open
I think this because when you're in an open space (such as starbucks) it's public for anyone to enter. I think.
