Textbender is a system of collaborative writing based on recombinant text. It implements a social Web medium with potential applications ranging from open art to open democracy. The underlying mechanism is evolutionary genetics: the text exists as a population of variants, one per author; authors swap fragments and arrangements of the text, peer to peer; and genes encode a traceable record of authorship throughout. Initial development is aimed at creative works, particularly at short verse and prose.
tmetaCalc is a scientific calculator for BlackBerry devices with a physical keyboard and OS 5 and up. It allows you to type the expression as it is, just like when you use dot-matrix scientific calculators. It has a few dozens built-in functions and constants, but you can always define you own functions. User-defined functions and constants are automatically saved. A typing assistant is provided. For example, when you type 'a', a list of function names and constants that start with 'a' is displayed for you to choose from.
