Has any one painted their basement floor in a decorative pattern.?

We are finishing our basement but cannot afford flooring, any ideas?Has any one painted their basement floor in a decorative pattern.?
One of the prettiest concrete floors I've ever seen was in a quilt store - they had made it look like quilts were lying around here and there - they had just used stencils.





One of the old diners in our town redid their floors, scraped up years of linoleum, and they painted back what looked like alternating black and red tiles.





I have a friend who paints murals - she did a basement play room - parts of it were set up for the little girl and it was just like a mini-house and then a mall, and the other end was done up for a boy with a race track and hiking trails. She also did a million dollar home - they wanted to keep everything natural - but the basement was an issue as they had this beautiful all woodfloored home, etc. and then this gray concrete - she painted a large Persian rug and then what looked like wood flooring at the outer edges.





So, just start looking at various flooring plans and then you can probably paint whatever you decide.Has any one painted their basement floor in a decorative pattern.?
My husband built a garage for a customer who wanted to use the space more like a porch. She rolled on a solid color of floor enamel, then taped off a grid of squared with masking tape. Then she spattered paint all over the floor with a darker color. When the tape was removed, it looked like a tile floor!
