Jamie and Samantha Shertick

Jamie Zach Shertick and Samantha Shertick are Australian-American twin artists, musicians, directors, writers, cinematographers, animators, voice actors and producers, born during Stuart and Zelda Shertick's vacation in Sydney, Australia.

History
During their childhood, Samantha was a big fan of Ghostbusters and loved Ecto-Cooler, Oreos and Crystal Pepsi, and usually created recipes that use them. She also has celebrated Crystal Pepsi's return and Ecto-Cooler's return. She also owns copies of early drafts of the scripts for Ghostbusters, Ghostbusters 2 and the infamous all-female remake of Ghostbusters.

In high school, Samantha played violin, piano, trumpet and other orchestral instruments fluently, and so, when she graduated in mid/late-2000s, she started making orchestral music as a freelance artist.

Personal life
Jamie runs a production company Jamie Shertick Productions, from his backyard in Burbank, California. Jamie lives there with his girlfriend Naomi.

Samantha has been dating Brenda Messerli since 2009, and married her in 2015, shortly after gay marriage was entirely legalized in the United States. When she and her brother Jamie were interviewed in 2016, Jamie revealed she came out as a bi in 2013, with his reaction recalled as "confused, but mostly proud".

Trivia

 * Jamie tends to wear socks of different colors, and sometimes pointy anime sunglasses.
 * On Twitter, Jamie mentioned he was a big fan of Homestuck (which he was introduced to by his sister Samantha) and Steven Universe. Because of it, he even wears a shirt with a Sagitarrius symbol on it, and has pieces of topaz and citrine (both his birthstones) at his home.
 * Homestuck was also the reason he practices rapping in his free time. During the panel session in Comic-Con 2015, Jamie, unexpectedly, did a cover of Alphabet Aerobics. He ended up rapping 2x faster.

The Time-Travelling Cat
Samantha created and currently produces an interactive web comic The Time-Travelling Cat with many people including: storyboard artists "Kaz", Demi Christine "DC" Young, Meijer van Wouters, and Wendy Brown, musician Jake Wrzesiński, Jamie Shertick, and other people, like writer/comedian Dan Aykyord, with many more. The crew consisted mostly of females, but there were also around 50 males.

The series stars a male cat called Zach (taken from Jamie Shertick's middle name), and his owner Brenda (named after Brenda Messerli, who is Samantha's wife, who also works as a musician for the webcomic), as they go on a huge time-travelling adventure, spanning across 8,000 pages, divided to 120 episodes, as of January 2017.
