rapid serial visual presentation

"Rapid Serial Visual Presentation (RSVP) is a method of displaying information (generally text) using a limited space in which each piece of information is displayed briefly in sequential order."... from wikipedia
Here is a simple rsvp reader written using Processing. Processing neatly hides the syntactic ugliness of Java and provides an event based loop and lots of useful functions for doing stuff. It also provides wrappers around the jar files for linux,mac and windows.

rsvp app packages linux , mac (I haven't tested this. My LC575 is not powerful enough for osx :-( ) , windows

Cobolt DP105 spec file for st2205tool

libst2205 and phack allow mini picture frames to be used as displays for lcd4linux, mplayer etc. The Cobolt DP105 mini picture frame I have doesn't seen all that common out in netland but in any case I followed the instructions in the "newhack.txt" and produced this spec file, put it in a directory as instructed and ran "assembleme". The hackfw.sh script then patched the firmware and it worked, yay.


;Spec-file for Cobolt DP105.
;Please keep the way the adresses are entered ($ to indicate a hex number,
;adresses in 4 digits) intact or the hackfw.sh script won't work anymore.
;Adresses here refer to file-adresses; in runtime these are loaded $4000
;bytes higher but that's accounted for in the hack-code itself.
