"Andy Warhol: Other Voices, Other Rooms" at the Wexner Center for the Arts in Columbus is surprising. It makes Warhol fresh again but also in some ways is far more exciting than the more prim-and-proper 2002 Los Angeles show, even though it has less of his classic artwork. It has important examples of his art but is vividly about his life and times. Through Feb. 15, 2009.

Eight-six thousand pounds and counting: add a few of your unwanted pounds ... of old technology. The Hamilton County Solid Waste Management District has already recycled that much computer equipment this year. There’s still time to add your old monitors, CPUs, hard drives, mice, keyboards, laptops and other assorted modern technologies. Take any of the aforementioned items to Technology Recycling Group (5139 Kieley Place, St. Bernard) 8 a.m.-4 p.m. Monday–Friday until Dec. 30. Hamilton County residents need to show proof of address — driver’s license, utility bill, etc. — to recycle equipment.

It is astonishing that Maria Lassnig, whose work is presented in an impressive solo exhibition at the Contemporary Arts Center (CAC), is widely unknown in the United States. She is an influential force throughout Europe, working in Vienna for the past few decades. Closed Tuesdays. Through Jan. 11.

With 300,000 new LED lights twinkling in the Festival of Lights display at the Cincinnati Zoo and Botanical gardens this year, the zoo will save $30,000 on their Duke Energy Bill. What that means in practical terms is enough power to supply 36 homes for an entire year. And the lights are cool, too. Open nightly 5-9 p.m. (closed Dec. 24-25). Guests can enjoy half-priced admission Dec. 1-3, 8-10 and 15-17.

Throughout the autumn, the walls of the new Iris BookCafé (1331 Main St., Over-the-Rhine), have been graced with black-and-white photographs by William Messer and Marc B. Suda. Selections from Suda’s Botanica Noveau series are assertive and austere in the midst of the elegance and quirkiness that is the café. The larger set of works by Messer roams through Claude Monet’s famous gardens in Giverny.

Although it’s highly specialized, the Lloyd Library continues to find ways for non-specialists to engage with their collection. In July, book artist Kate Kern served as artist-in-residence at the Lloyd Library, funded by a grant from the Ohio Arts Council. The library invited local educators, scientists, students, artists, librarians and others to take part in Kern’s residency program. Thirteen works of art, made mostly — and remarkably — by non-artists, now represent the workshop participants in The Alternative Field Guide, on view in the Lloyd’s gallery Monday-Friday through Dec. 30.

Santa Claus is coming to town, and he’s delivering flowers to all the good little boys and girls. This year the Krohn Conservatory is celebrating 75 years of their Holiday Floral Show with An Old Fashioned Holiday. Designed by landscape-extraordinaire Tim Young, this season’s winter wonderland reflects the amazing history of Cincinnati through Young’s replications of neighborhood street parks, all decked out for the holidays. Visitors can spot new varieties of poinsettias on display along with traditional plants like pines, spruces, bayberry and boughs of holly … fa, la, la, la, la, la, la! In addition to the holiday foliage, mini Cincinnati landmarks and historic park architecture will be placed in and around the community square. Show is open daily from 10 a.m.-5 p.m. through Jan. 4.
