I got Engineering Gifts: Stay Positive Work Hard Dream Without Limits Printable, Office Wall Art, Inspirational Printable Art, Nerdy Gifts and is a set of 3 printables that say "Stay Positive - Work Hard - Dream Without Limits" using mathematical symbols.
My Opinion: These are 8X10 prints and just need to be put in frames for gift giving. I like them and like seeing the math symbols.
As an engineer and blog owner of Engineering Expectations, Meagan Bukowski often wanted to have chic decor that was subtly geeky. Unfortunately, this is hard to find. Therefore, I created motivational wall art using equations!
