On the cover of the greeting card, envision a swirling orchestration of vibrant shapes and chaotic colors, drawing inspiration from the explosive energy of a "waaagh ork" birthday party.

In the center, a distorted, abstracted cake towers in multiple layers of chaotic splatters reminiscent of Jackson Pollock's frenetic strokes. The layers of the cake cascade with irregular geometric forms in deep orcish greens and fiery oranges, contrasting with wild electric purples and reds. Large circular confetti—echoing Joan Miró's whimsical dots—scatter across the card in a multitude of sizes, with each piece bearing a different hue: cobalt blue, lemon yellow, and vermilion red.

At the top, a dynamic sky takes shape through Wassily Kandinsky's influence, where concentric circles and geometric lines in primary colors collide and interact. A triangular banner, cutting through this vivid sky, stretches across the top right corner of the card, painted in a deep orky green, the letters "Thadius" scrawled in bold, chaotic white brushstrokes reminiscent of Cy Twombly's lyrical lines.

Below, an abstract representation of a horde of orks is depicted in deconstructed shapes and colors akin to Willem de Kooning's expressive forms, using heavy, crude brushstrokes. The orks’ forms blend into the busy background, each ork hinted at through splashes of viridian green and muddied brass, barely contained within their contours.

The entire scene is framed by Piet Mondrian-like intersecting black lines, though they waver and curl unexpectedly, evoking the sense of chaotic celebration and mirth. The background behind this pandemonium is a Rothko-esque expanse of blurred colors, a gradient of dark violet to bright orange, suggestive of a fiery, festive atmosphere.

This composition, steeped in the kinetic energy of an orkish celebration, marries the abstract with the palpable, culminating in a captivating birthday scene that defies order, just like the grand Waaagh!
