You can try imagination from the repository.
sudo apt-get install imagination
Imagination is a lightweight and user-friendly DVD slide show maker with
a clean interface and few dependencies. It only requires the ffmpeg encoder
to produce a movie to be burned with another application.
It currently features over 50 transition effects. Exporting the slideshow in FLV format is supported as well.
kdenlive is more like a video editor which supports lots of audio/video/images formats, including mpg, flv, ogg, jpg, mp3, avi, wav, etc.
It is more like Sony Vegas in Windows and it allows you to merge between file formats/sources, this way you can put an image with transparency over a running video, change original audio and include effects, transitions, pan, zoom, crop, and other video effects. Color correction is also supported and it works project based, which allows you to create full scenes in a project and insert projects in a final project without rendering.
Some screenshots of my desktop are provided here to illustrate what you want to do: I am placing a png with transparency image over a video, zooming and positioning over the video.
Here we can see the media tracks, a video and a png image.
In this screenshot I am using pan and zoom plugin in order to resize and position the png over the video.
And we are using the composition video transition all over the png image's duration in order to place it over the video.
BTW: Pan and Zoom and other interesting plugins/video effects supports automation, which is useful for your desired "to put images on my hand (in the video) and have them fly all over the video"
A video editor is what I suggest you for this task, any of them are fine but if you are used to Movie Maker, Sony Vegas, Adobe Premiere, and these kind of software, you will feel comfortable when using kdenlive.
Good luck!

The
transcode
package bundles an image stabiliser plugin vid.stab. Their video demo certainly looks convincing (if a little vomit inducing).
