I've created an experimental toy programming language with a (now) working interpreter. It is turing-complete and has a pretty low-level instruction set.

Even if everything takes four to six times more code and time than in PHP, Python or Ruby I still love programming all kinds of things in it.

So I got the "basic" things that are written in many languages working:

• Hello World
• Input -> Output
• Countdowns (not as easy as you think as there are no loops)
• Factorials
• Array emulation
• 99 Bottles of Beer (simple, wrong inflection)
• 99 Bottles of Beer (canonical)

• Conjatz conjecture

• Quine (that was a fun one!)

• Brainf*ck interpreter (To proof turing-completeness, made me happy)

So I implemented all of the above examples because:

• They all used many different aspects of the language
• They are pretty interesting
• They don't take hours to write

Now my problem is: I've run out of ideas! I don't find any more examples of what problems I could solve using my language.

• Do you have any programming problems which fit into some of the criteria above for me to work out?
