Speed of LightLimited edition print
by Sam Grudge
There are moments when love doesn't walk through the door — it tears through it. Speed of Light is my attempt to paint that feeling: a red heart moving so fast through space that the world around it dissolves into pure energy. The burst of light radiating from its core, those brushstrokes stretching outward in every direction — that's not decoration, that's physics. That's what it does to a room, to a day, to a life. Bold red against a deep cosmic blue, raw acrylic texture you can almost feel with your eyes. If love has a velocity, I think we both know it doesn't slow down.
A numbered, hand-signed limited edition print of Speed of Light, produced by Colorfields in Belgium on Fine Art Canson rag cotton paper and supplied with a certificate of authenticity.
