My name is Marshall “Gripp” Gillson and glassEyeballs is my company.

I started it several years ago as an umbrella over my semi-professional art career. I also work professionally as a computer programmer. This page has nothing to do with that.

My art explores race, mental health, loneliness, existential dread, and sometimes robots. It is often also explicitly opinionated and political.

If you’re on this page, I assume it’s because you’re looking for information about me and my artistic endeavors. So let me give you some.


A short screenplay I wrote called Handstyle was a semi-finalist in the Hollywood Just4Shorts Film and Screenplay Competition. Another of my scripts, called Shyla, was selected as the Grand Jury Prize winner of the Bolt by Barnstorm short screenplay competition. That script was filmed this year. I’m currently shopping it to festivals.


Between 2008 and 2017, I was an active slam poet. I joined nine teams in five cities (Salt Lake City, Atlanta, Providence, Cambridge, Boston) in competing at the National Poetry Slam (NPS). I performed on final stage at the event in 2016 and 2017 as a member of the House Slam team. I was a member of the winning team at the Vox Pop poetry slam tournament both of those years as well. In 2014, I placed 15th at the Individual World Poetry Slam (IWPS) representing Providence. You can find videos of my performances on YouTube. In addition to performance poetry, I self-published five chapbooks in print and one digitally. My written work has also been featured in a number of journals and anthologies.


In 2017, I originated the role of Nathaniel Greene in A Furtive Movement: The Use of Farce at the AS220 black box theater. I have also recorded performances for a few student films and one web series, all forthcoming.


From 2001 to 2016, I frequently performed as a rapper. Under the moniker Gripp, I released five albums (Ansible, Head in the Cloud, Grass Nap, As Knowledge Kills Beauty, Mind Over Matter), three mixtapes (mixtape #3, Doing the Most, No More Excuses), two EPs (Gripp Makes… Bad Decisions, Aquarium), and two compilation albums (The Unarmed Truth, The Tape). I’ve also featured on a lot songs for a lot of other rappers. In April 2012, I was interviewed on The Skeptic’s Guide to the Universe regarding atheist/secular humanist activism in my music. Since 2016, I have only sporadically released individual songs. I still have an active SoundCloud page, though I recently purged it of all of my old music.


The easiest way to contact me about my art—including press inquiries, booking requests, and general questions—is by sending an e-mail to If you just want general updates on what I’m doing artistically, you can find me on some social media. I’m currently using TwitterInstagram, YouTube, and SoundCloud. Note that my social media profile fluctuates. I disable and reenable platforms frequently. I’ll try to keep this list up to date.
