「HEAT WAVE」は FontVibe AI で作成した溶けるフォントの文字エフェクトです。下から液化していく艶のあるオレンジレッドの文字。溶けた滴、ゆがんだ下端、暗いチャコールの床に光る水たまり。

letter material liquefying and flowing downward under heat — lower portions lose structural integrity, edges softening and rounding outward as gravity pulls the molten mass down. Multiple drips of varying thickness: one to two thick primary flows with slight bulge at origin and teardrop termination, two to three medium streams, fine capillary trails between them. Surface tension visible at drip necks. Viscous pooling accumulates at the letter base with a faint wet-surface sheen. When no specific material is defined, the default melt color is warm amber-to-deep-orange — the natural thermal color of heated translucent material. YouTube thumbnail mockup in a browser (16:9).
