Dalek Christmas Tree Cards & other Doctor Who geekery

The Dr. Who Dalek Tree cards by Etsy seller babywalls are ideal for spreading the Dr. Who spirit during the holidays.

Circuit Snowflake Cards

The Circuit Snowflake Cards at Fractal Spin are perfect for sharing the holiday geek spirit!

Cute Custom Chemistry Cards

Etsy seller zozoscards sells sweet chemistry greeting cards that you can have personalized with your own caption.

Printed on a 4" x 6" 260gsm white card with a linen finnish with high quality Epson inks.

The caption on this card can be whatever you like. This could be a card for a science graduate, student, or perhaps a love card to a girlfriend or boyfriend. Chemistry is different for everybody :D

American Scientist Stamps

I know snail mail is totally 20th century, but occasionally it's nice to send a message on a physical piece of paper. When you do, why not use stamps commemorating great American scientists, including the Nobel-prize winning biochemist Gerti Cori. The stamps are available from the USPS.

Mathematical Quilts & Note Cards

Elaine Krajenke Ellison is a mathematics educator who makes lovely mathematical quilts. While the quilts are all one-of-a-kind (and some are in museums!), you can order note cards with full-color images of her artistry. Some of her quilts are for sale, and you can contact Ms. Ellison through her site for more information.

Show above: The Clifford Torus, The Six Trigonometric Functions, Spiraling Pythagorean Triples.

If you haven't already gotten a Valentine's day card for your geek girl, and she has a mathematical bent, you might print out one of these heart-shaped algebraic surfaces from the Wolfram Demonstrations Project.

Dopamine is responsible for the euphoric feeling of being in love. What better symbol of your feelings on Valentine's Day? Made with Molecules has special-edition dopamine necklaces with a heart for Valentine's or simple dopamine jewelry for a great gift any time!
