JSpice is an implementation of the OpenSpice programming language specification. OpenSpice is an attempt to make the features of a powerful modern programming language accessible to occasional programmers.

It is written in pure Java and the goal is to be a complete implementation of the OpenSpice. As it matures, the focus will shift to the implementation of a general web services environment codenamed "Palantir". All performance considerations are deferred for later consideration - and this will always be compromised by the Java Virtual Machine. However, as demonstrated by MillScript, we should be able to achieve excellent integration with Java classes.
