Tools for careful work and curious minds.

Tony Crayfish Evolution

Your living evolution lab. Watch colorful creatures feed, compete and reproduce in a virtual pond. Inspect chromosomes, follow descendants, edit genomes and explore how inherited traits shape survival.

Compare reproductive strategies in controlled experiments, or tackle four challenges: Pond Biomass & Diversity, Establish a Lineage, Mount Improbable and Combination Mount Improbable. Explore genetic diversity, food webs and adaptation through visual reports, or relax with full-screen ponds and gentle sound.

All simulations and experiments run locally on your device. The app uses simplified biological models; outcomes emerge from the simulation rather than guaranteeing a balanced ecosystem or a winning reproductive strategy.

Tony Crayfish BioMatch

Match molecules. Defend your science. Publish the paper. A biology-inspired match-3 puzzle game with cascading matches, special pieces and 12 research encounters.

Run gels, balance a centrifuge, contain contamination, pair proteins, pattern an embryo and face Reviewer 3. Play without time limits, save your campaign, or choose any experiment in Practice Lab and challenge your local best times.

Tony Crayfish Worm Genetics

Explore C. elegans genetics in a hands-on simulation. Start with an EMS mutant, clean its genetic background through outcrosses, then use visible phenotypes and recessive markers to map a hidden causal mutation.

Compare two-factor and three-factor crosses, follow worms across plates and named strains, and test your map position before revealing the answer. Choose a Ted tail defect visible in hermaphrodites or a Pha pharynx phenotype visible in both sexes.

Tony Crayfish Genetics Primer

Discover genetics by changing the experiment. Twelve interactive laboratories explore Mendelian inheritance, exceptions to Mendel, genetic mapping, epistasis, quantitative and population genetics, inbreeding, GWAS, polygenic scores, coalescence, effective population size and LD blocks.

Follow a step-by-step animated tour, observe illustrated phenotypes, reveal Punnett squares and explore published human-variation data. A searchable glossary explains 168 terms, abbreviations and scientific symbols.

Tony Crayfish Biophysics

Explore how complex form, pattern and behavior can emerge from simple local processes. Twelve interactive laboratories and a sixteen-chapter animated tour illustrate Turing patterns, spiral growth, self-assembly, cell sorting, chemotaxis, biological condensates, lipid membranes, networks and canalization.
