Glass Shatter Hover

Set [TEXT] in bold wide letters made of cyan-to-violet tinted glass with bright bevel glints and a soft inner glow, fused into a faint glass sheet over near-black. At rest a slow invisible touch drifts across the pane, leaving hairline white cracks along a triangular fracture pattern that heal behind it and chipping out a single shard now and then. On hover the pointer cracks the glass wherever it goes, and fast swipes knock triangular shards out of the pane in the swipe direction: they fly, tumble and glint with cyan edges, start to fall, then snap magnetically back into place, the cracks fading until [TEXT] is whole again within about two seconds. A press punches a radial shatter burst out of the pane. On touch screens the finger cracks and shatters it the same way.
