Many. However I only use a few of them, because they're practical. Right now I can think of three effects that I actually use.
- Pentagon Sandwich: originally offered as a PDF on the Dananddave forums, with a video posted on my YouTube channel, the handling has since been streamlined, yet retaining the effect. Not very original, but the handling is. Works very well for laymen. (keep in mind, if you have seen the video, it's really old, and has way too many unecessary actions compared to the present handling, which is quite natural.)
- Toast: a sandwich. A clean one. Method has been dubbed EVIL by Kevin Ho. This one gets magicians too, if that's how you want to spend your time instead of valuable practice time.
- Charing Cross: a two-phase transposition that actually makes sense for once. Why cards switch place, and how it happens. With a little kicker. another great layman-entertainer.
I don't intend to release them in a product. ever. because I don't believe anyone would gain anything from buying my "material". I do however share ideas with close friends and hope they gain something from it, the way I gained from playing around with the material.
