Sebastian's formative years unfolded against the backdrop of political and socio-economic turmoil in eastern Poland during the 1980s and '90s. Remarkably, at the tender age of seven, he embarked on a journey into the realm of imagery, finding solace and expression through an ATARI® 130XE™ computer. Coping with dyslexia, he discovered his unique way of comprehending the world—immersing himself in television programs and films that significantly influenced his creative style. Reflecting on those early days, he recalls, "I would watch TV for hours, absorbing it all. The colors seemed so bright." After pursuing studies in IT and computers in Warsaw, Sebastian transplanted himself to London, where he completed his education at Kingston University. His trajectory led him to become an assistant to Mat Collishaw, a prominent figure among the Young British Artists alongside Damien Hirst. Concurrently, the burgeoning accessibility of 3D-printing technology empowered him to seamlessly fuse his technical acumen with his artistic 3D expertise. Sebastian's iconic POPek series, initially conceived as a satirical nod to the contemporary American artist Jeff Koons, transcended its origins, encompassing various poses, from yoga dogs to those engaged in bodily functions. The collection gained notoriety in 2012 when the London Underground deemed it 'offensive' and barred its display at the Art Below exhibition in their stations. In his Gone series, Sebastian resurrects cherished childhood heroes such as Mickey Mouse, Lisa Simpson, Winnie-the-Pooh, and Buzz Lightyear. Evoking a haunting ambiance with shadowed imagery, these artworks explore "the dark side" while simultaneously evoking a profound sense of nostalgia. Sebastian elucidates, "It’s showing our childhood heroes reaching out to us with an extended hand and saying, 'Hello, I’m still here, do you remember me?' Or if those are fading memories, they are saying goodbye." Sebastian's artistic endeavors have found a home on a global stage, with permanent displays at the Singapore Science Centre and appearances at art fairs spanning Hong Kong, Los Angeles, New York, and London. Notably, in 2021, his large-scale dogs graced Covent Garden in central London, raising £1,160 for the Blue Cross pet charity. These whimsical canines have also contributed to fundraising efforts at Birmingham Dogs' Home and Birmingham Children's Hospital. Describing his work as innovative, modern Pop Art, Sebastian situates himself at the nexus of the contemporary Pop Art landscape, proclaiming, "My work fits exactly where we are now in this modern Pop Art world."
