Shopfront: Something to try for spring: plant some flowers or bulbs in a clear glass vase to make a feature of the soil below, not just the bloom on top.
Anything with a wide neck makes for easy planting - you could even try fish bowls and pasta jars - and a simple decorative display for any room: try a group of three or four on a chimney piece or window sill. It's all the better if the glass containers look different from one another.
