Next up in our series about geeking up Valentine’s Day, here we have a collection of awesome Valentine cards from Etsy. Why just say “I love you” when you can express your love in geekier ways?  Click on the caption to visit the store listing!

I wish I was your derivative so I could lie tangent to your curves.

I’d take an arrow to the knee for you any day.

You are the Na+ to my Cl-.

I would never drop you into an Emergency Intelligence Incinerator.

I love you because of these silly hormones.

Even during a zombie apocalypse I’d still chews you.

My love for you is like a circle, it has no end.

My love for you has no bugs (just random features).

Without you my hearts are empty.

I would give up my superfast Internet for you (for the weekend).
