Here is an idea for a vertical garden in a classroom (plus a fish tank). This could also work in other places -- homes, places of worship, community centres, etc. Maybe even outdoors? With a mesh covering over the fish tank, the cats couldn't get in.
I love having fish but hate ugly tank stands. I always think of those really ugly metal things that look like they belong in your grandmother's house. I was lucky to find this one that blends in quite nicely with my things.
Some piece of summer and jungles for you) I love that bright big flowers, birds and colors. Cool to use as a wallpaper for your phones. Plus some nice examples of floral and tropical pattern on walls, furniture and clothes. Enjoy the summer!
