Let's say you want to have something more personal than just wall art. When stuck at home in March, but having access to a computer, I did this. I bought 24 of these 8 x 10 picture frames with glass fronts. They were 6 for $15 on Walmart's website, they've gone up, now they're $18.99 for a 6 pack and orders of $35 or more get free shipping.

I bought pictures on eBay of old TV shows and movies that I liked and wanted to remember, most cost between $4 and $9. You could use family photos, or those you took on a trip, and or photos you would like to buy online of subjects like flowers, or whatever. Here's how mine turned out. I had a section of wall that I wanted to fill with something, so I used them there. You don't have to buy 24, do just 6 or 12 if you want above the table.
