Pocket Scheme gives your PDA a standalone programming capability in Scheme, a dialect of Lisp with exceptionally clear and simple semantics. It supports file creation and manipulation, arithmetic operations of unlimited precision, the complete Unicode character set, data sharing via the Windows clipboard, regular expression matching on character strings, simple TCP client and server networking, scripts written in Scheme, and even direct system calls to the Win32 API.

Snow aka Scheme Now
Scheme Now!, also know as Snow, is a repository of Scheme packages that are portable to several popular implementations of Scheme.
Snow is a general framework for developing and distributing portable Scheme packages. Snow comes with a set of core packages that provide portable APIs for practical programming features such as networking, cryptography, data compression, file system access, etc. Snow packages can export procedures, macros and records.
BDC Scheme
A Scheme interpretter written in Java that uses some compiler-style optimizations for better performance than straightforward interpretters. Originally started in 1996 as a project to learn Java programming, BDC Scheme was used as an extension language in a commercial product starting in 1997. Previous to open source release in 2002 it was written up as part of an a MIT MEng thesis in 2000 where it was referred to as Script. The thesis covers the history of the implementation and benchmarks the performance relative to a variety of other Scheme implementations, both Java and non-Java based such as Kawa, Silk, Skij, Scheme 48, MIT Scheme. Both Sun and IBM Java virtual machines are used in the comparison.
Scheme Links
Here are some links to Scheme information sites. I haven’t heard of many of the distributions listed. For example, Scheme on the Palm Pilot!

- RNRS
- Free Schemes
- SchemeWiki
- DMOZ
- Commercial Implementations (interesting for historical reasons)
The Scheme Programming Language Standardization Experience

HOP Web Framework
HOP is a new Software Development Kit for the Web 2.0. It relies a new higher-order language for programming interactive web applications such as multimedia applications (web galleries, music players, …), office applications (web agendas, mail clients, …), ubiquitous domotics, etc. HOP can be viewed as a replacement for traditional graphical toolkits. HOP is implemented as a Web broker, i.e., a Web server that may act indifferently as a regular Web server or Web proxy.

One programmer’s Scheme bookshelf
Here is one programmer’s Scheme bookshelf.
It provides a good overview of a lot of the best material out there, along with the authors opinions on all of it.
Why are there multiple let statements in Scheme?
There are multiple members of the let family in Scheme to communicate your intention to the reader!
Here is a good post on the matter.
