Animatronic Butterfly Completes Wedding Day Look
I think this is a neat project, although there must be a pretty small subset of potential brides who would be interested in this. How could it be improved? Mostly by making the non-butterfly portion of the thing smaller.
Some commenters suggested memory wire in place of the servo. Memory wire, or shape memory alloy , has one shape at room temperature and takes on a different shape when heated or cooled. In this application the heat would have to be supplied by electrical current. You can find the electrical and mechanical properties of the material online. I will leave it as an exercise to the reader as to whether the thinnest available wire would present too much current draw for a small battery.
The battery is another area for improvement. The author considered a rechargeable lithium-ion battery but ended up using a 2-cell AAA battery pack. A better choice would have been a Lithium coin cell. With capacities up to 1000mAh, the larger ones would outlast the AAA battery pack while being much smaller.

“I wish that every time he touched me left a mark,” Anderson repeats on “Marked,” sounding like an Exile in Guyville Liz Phair; “20 kisses with a butterfly knife” reads like a cast-off lyric from Tom Waits' Blue Valentine. There's blood, jealousy
