The Periwinkle Foundation's Annual Cycle for Life

If your conscience needs an overhaul, the Periwinkle Foundation's 18th Annual Cycle for Life, presented by White Oak Energy, is your ticket to killing all those birds with one stone — at the same time.

The indoor bike-a-thon encourages teams to spin in four, 30-minute intervals and raise a minimum of $250 or $1,000 per foursome. At the sporty affair, funds will also be raised through a silent auction alongside children's games and family activities.

Houston Lebowski Bash 2013

I don't get it. I just don't get it. But as they say, if you can't beat them, join them. Truth be told, film buffs who have an adoration of the 1998 cult classic, The Big Lebowski, are a ridiculous bunch who are a delight to be around. Don't you think you need an injection of positive, be-who-you-are attitude?

Fans are sure to dress as their favorite character to partake in a trivia game, followed by a screening of the movie. It's recommended that guests bring a lawn chair or blanket, and cash to purchase beverages on site.

Da Camera's 25th Anniversary Season Gala "Cabaret Da Camera"

When she looks back a quarter of a century, Da Camera artistic director and founder Sarah Rothenberg is both proud and boggled by the trajectory of what began as an itty-bitty nonprofit, now a puissant force that's a critical part of defining the ethos of Houston's art scene. Da Camera's silver anniversary didn't arrive without blood, sweat and tears, so it's befitting that gala chairs Ann and Don Short want to party like a rock star.

With former Allman Brothers and Rolling Stones keyboardist Chuck Leavell and friends, plus dinner by executive chef John Signorelli, "Cabaret Da Camera" will raise funds for the organization's education and community ventures, including the successful Young Artist Program. Jennifer and Josh Gravenor chair the after party, a late night carouse that promises a wicked buffet, dessert bar, cigar bar, cocktails and a silent auction.

The deets: Saturday, 7 p.m.; St. Regis Houston; individual tickets start at $500; after party begins at 9:30 p.m.; tickets start at $60 per person, $100 per couple.

Williams Selyem Wine Dinner at Philippe Restaurant + Lounge

Sommelier Vanessa Trevino Boyd is a walking encyclopedia who can spew info about any potation or fermented beverage that makes her guests smile from ear to ear. It's fun to try to stump her, though more likely than not, you will be on the losing end. The savvy wine steward will host a wine reception that welcomes Bob Cabral, director of winemaking and general manager of Williams Selyem Winery of California, followed by a five-course meal with pairings.

We hear that two older wines from the collection and a rare bottling of Brut Vintage Sparkling Blanc de Noirs may be sampled that evening.

The deets: Sunday, 5:30 p.m.; Philippe Restaurant + Lounge; tickets are $175.

Arts smarty pants and in-the-loop creative maven Nancy Wozny's pick: Trees by Beth Secor

Nancy says: "There's nothing quite like being in a room full of Beth Secor's trees, which is exactly what I got to do at Inman Gallery as part of Trees, running through March 20. Secor's meticulous workmanship, delicate marking making and subtle use of texture and color make me forget that Houston suffered such a devastating loss during the drought, a catastrophe that also factors into Secor's images.

"Also catch Farewell Ruins in the front room, with Julia Haft-Candell and Julia Kunin's fabulous new ceramic work. I found Haft-Candell's biomorphic sculptures combining clay and hand sewn fabric especially enchanting."

The deets: Through March 20; Inman Gallery; admission is free.
