Create a typographic design featuring the word ‘Serendipity’ with a 1970s-inspired, psychedelic font style. The text should have thick, wavy, and interconnected letters, forming a bubble-like, organic shape. The letters should have a soft, rounded, and fluid design that feels playful but clean. The font should have uneven thickness in some parts, almost like it’s melting or expanding slightly. Keep the design all black, no color at all, on a white background for a minimalist contrast. Ensure the overall look captures a retro, groovy, and slightly abstract feel, the spacing between the letters should be tight and compact for a cohesive look.
