For Robert Sibrizzi, of Bayside, Christmas begins in April. That’s when he starts work on his holiday decorating extravaganza, which spills over next door, onto his mother-in-law’s lawn, along 205th Street.

This year’s effort includes 500 decorations and 70,000 lights that blink in time to whatever music he’s playing, via his new computerized synchronization system. Sibrizzi also has added a surprise feature: a bubble machine.

“So when I see people walking by the house, I turn it on and the whole driveway fills up with bubbles,” said Sibrizzi, 46.
