Sorry it took so long, but the April libraries are ready now. Most of the emitters were created by Elvis Deane and Tom Granberg, so I have to thank them for their help. Elvis made his (I believe) during some free moments in the wondertouch booth at NAB last month, and Tom spent a couple hours in the booth making his emitters as a sort of "live demo" of the emitter creation process. I had so little time before, during, and after the show, that I only contributed 3 emitters this month (well, I did a couple more, but I forgot about them until I had already uploaded the library, so they'll be included next month).
The libraries are pretty big this month, due to the fact that both Elvis and Tom used some fairly large animated images in their emitters.
