I never ever seen this type of work i like your work that ,s great work u done it..hii i am doing interior designing...

You know...using some gasket material glued to the bottom you could have them stand on their own.  Then you could use them to force crocus or paperwhite bulbs during the winter.  Or fill a bowl with some corks or gravel and poke the bulbs (gently!  lol) at different angles.

So clever :)  I would never have thought of using lightbulbs this way.

Fabulous!
