Portalboard

a mystical mechanical keyboard floating above a cracked obsidian pedestal, each key a hovering shard of luminous crystal etched with glowing runes. No physical frame, the keys levitate in perfect QWERTY formation, with arcs of energy crackling between them. The space bar is a long, glowing shard containing a swirling galactic portal. When a key is pressed, shimmering ripples radiate outward, briefly opening tiny portals above the keys that reveal glimpses of alien landscapes, cosmic nebulae, or strange cities. The chamber is lit by shifting blue, purple, and gold light patterns that dance across carved stone walls, with swirling magical energy rings hovering around the keyboard. Ultra-detailed textures, cinematic lighting, volumetric fog, slow camera pan, and highly dynamic fantasy–sci-fi atmosphere.
